On Monday 28th October Community The Complete Fourth Season comes to DVD in the UK, and that means every episode ever broadcast will be available from the cult college comedy that stars Chevy Chase, Joel McHale, Alison Brie and Donald Glover among a vast ensemble of crazy characters in crazier situations. So now you have no excuse to not catch up with one of the most exciting and adored sitcoms in the last decade, we've decided to provide you with ten important episodes from the entire run that will explain why Community is the funniest show on television.

Let us begin.

Environmental Science - Season 1 Episode 10

One of the first episodes of the show where Dean Pelton (Oscar winner Jim Rash often in crazy costumes) puts on a big Greendale Community College event/dance for spurious reasons, in this case to fit in to environmental awareness week. But the main plot sees study group leader Jeff Winger (McHale) taking a bullet for everyone when Spanish teacher Ben Chang (Ken Jeong) forces everyone to do insane amounts of work. Winger gets involved with Chang's social life when Chang's wife throws him out, and Winger and Chang become bros, but to the detriment to the rest of the class. Meanwhile crazy pals Abed and Troy (Danny Pudi and Donald Glover) try to look after a rat, with mixed results, and Shirley (Yvette Nicole Brown) takes a lesson from old coot Pierce Hawthorne (Chevy Chase) in public speaking for a class. It's a hectic 22 minutes full of odd plot twists, character beats, weird humour and a wonderful musical finale. Community took time to find itself, but by episode 10 it was really going loco. Which is Spanish for amazing, if you were taught by Ben Chang.

Investigative Journalism - Season 1 Episode 13

The characters of Community are very stringent and rarely do anything out of step with their selfish nature, so when Jeff is given the post of editor for the Greendale campus newspaper, he becomes the selfish, lazy Jeff Winger we know, only with an office and an attitude for deadlines. Annie (Alison Brie)  is the go-getter journalist with ethics and a deep, impassioned story of racial profiling in the college that threatens Jeff's glamourous position. Meanwhile guest star Jack Black is mysteriously part of the study group, and ruins everything he touches. It is silly, weird and very very funny stuff, full of self-referential jokes, early shades of the meta comedy that Community would later coast on, and with a lot of fun with the characters thrust into a storyline that they wouldn't usually be thrust into.

Contemporary American Poultry - Season 1 Episode 21

You'll have heard a lot about how Modern Warfare, the paintball episode, blew Community out of the water and into amazing sitcom territory, and we'll get to that later, but before that there was an episode that saw the study group vie to get the chicken fingers that everyone in college wants, which means a grand scheme to take over the cooking, the dealing and everything in-between. It's organised crime in a small small scale, and Jeff Winger feels power slipping past him when cook Abed finds that he can control the chicken fingers without Jeff's help. And an inspired Goodfellas riff throughout the episode hedges this episode close to the annuls of classic sitcom episodes. It's solid gold through and through, and introduces us to Community's monkey character Annie's Boobs (Played by Crystal, who you will have seen in Night At The Museum and The Hangover Part II). Pure slice of fried solid gold.

Modern Warfare - Season 1 Episode 23

This is the episode everyone talks about. Things go badly when the Dead announces a big prize for the winner of a paintball contest in Greendale, and the school becomes a post-apocalyptic world of tribes and hunting packs. The study group finds an uneasy united front as they survive assaults from the AV Club (Easy meta joke), Glee club and a Disco Rollerskater, all for this glorious prize, one to make everyone go nuts. But as big and as broad as the episode goes, the heart is strong, and Jeff and Shirley, who have few but very good storylines together, are a great duo to bounce off one another's ideals, with Shirley the caring mother and Christian, and Jeff the angry, cynical single man. Meanwhile everyone gets to do fun action beats, except Chevy Chase who throws in the towel early and makes for better comedy.

Epidemiology - Season 2 Episode 6

Despite the harsh name of the episode, the second Halloween episode in Community's run is very simple. During Greendale's Halloween party (With a song mix consisting of ABBA tracks and the Dean's brief voice thoughts) the food, from an army surplus, seems to change folk who eat it into infected, mindless creatures interested only in biting those not infected. So it's a zombie thriller with Halloween costumes, a slew of horror cliche riffs, including a cat jumping out a few times, and the start of a storyline that sees Shirley become a mother once again, and the possible parent is one horrifying option. It's a cinematic episode that brings the jokes fast and thick, with a George Takei narration, non-stop Abba tracks and jokes upon jokes about film and TV horror, jokes that really never get old. This is what Community was doing in its moment of pure perfection.

Cooperative Calligraphy - Season 2 Episode 8

What is a bottle episode? It's when a show only uses its main cast in sets already built to cut costs on budget, so other episodes can be produced without worrying about spending too much. Community does a bottle episode, which they make references to frequently, as the study group hold themselves in the study room to find out who stole Annie's pen. The group turn on each-other because at times these characters are as mean as the gang from Always Sunny, and as secrets come out and the possibility that the missing pen may be a manifestation by Annie to keep the group together, tensions get high. It's a character episode that Community can do so well with great writing and all the performers really nailing their roles, and the return of a certain animal we all know and love (Read above). Simple sitcom tropes dragged to crazy extremes, and hugely hilarious to boot.

Advanced Dungeons & Dragons - Season 2 Episode 14

Community is a show made by nerds for nerds, which is why they can deliver an episode of TV that centres around the study group playing D&D, for the purpose of making suicidal student Fat Neil feel better about himself. And whilst the group, led by dungeon master Abed, flex their inner imagination, Pierce feels like he's being left out, and becomes something of a mega-villain in this episode. After a Christmas episode that took the form of claymation, this one decides to avoid all realms of fantasy and shows us D&D from the tabletop perspective, and the adventure is still a fun, and thrilling, ride. When Fat Neil faces of against Pierce in the real fight of good versus evil, the show finds ways to make every inaction a moment as it would be in a feature film, and it's an immense job in making it not at all be awful or awkward. Another gem that Community manages to make out of potentially hazardous material, and with a twist that is dark and understandable for the characters, this is one of the key episodes you'll be seeing on top 10's of this show.

Paradigms Of Human Memory - Season 2 Episode 21

After a bottle episode earlier on in the season, it feels like this episode is also going that way, but all of a sudden it becomes clear that Community is pulling a clip show. A clip show of clips that never happened, that we never saw, including a story where the study group stayed overnight in a haunted house, built a home for humanity, went to a worryingly racist ghost town and drove a locomotive, a locomotive that's "run on us" as a montage of Jeff Winger speeches tells us. From jokes about youtube fan videos to the revelation that Jeff and Britta (Gillian Jacobs) may have been dating for a while now, to clips of the study group in strait jackets, it's a truly crazy, weird episode, one that fits the heightened comedy world of Community, and whilst it's not as emotionally strong, it's an out-there hysterical episode and an all-time classic.

Remedial Chaos Theory - Season 3 Episode 3

An episode that starts with a joke about the episode number based on the apartment number being incorrect compared to the broadcast number of the episode is going to be one that lunges for the big nerds in the audience, and it is one of the craziest episodes of the show. When the study group can't agree with who should get the door for the pizza guy, Jeff rolls a dice, and in Abed's eyes forms a series of parallel timelines in-which this one decision changes the fabric of each world. This means that when Troy has to get the pizza, Pierce ends up with a hole in his leg, the place is set alight and The Darkest Timeline is created. Full of jokes, snippets of storylines fans want but will never truly see, and a lot of cracks at Shirley's cooking and Pierce's inappropriate storytelling, it's a silly episode with a genius goal, and an episode that is as delightfully weird as it is surprisingly sweet. Excuse us as we throw on Roxanne and sing along.

Documentary Filmmaking: Redux - Season 3 Episode 8

In season 2, film obsessive Abed took the study group into the world of documentaries, in a smart takedown of the recent mockumentary sitcom shows, such as The Office, Modern Family and Parks & Recreation. This time, the focus is away from mocking mockumentaries (mockumockumentary?) and instead  to a take on the documentary heart Of Darkness, which saw Francis Ford Coppola's descent into madness as he filmed Apocalypse Now. The Greendale TV ad is old and needs to be redone, Dean Pelton feels like he can do a good job, and gets the study group involved, but as he manages to get former student Luis Guzman to come and film a snippet of the ad, Pelton gets specific and abstract in his directorial requirements. And everyone else begins to get angry at the madman. The episode is weird and dark and absolutely hysterical, and shows up the Dean as a more rounded character than his camp, costumed entrances in other episodes allowed. The Dean's lowest ebb and another disaster for the school to try and rebuild from, it's one of season 3's weirdest episodes, and it's a weird season, but one that is entirely brilliant from start to finish.

Pillows And Blankets - Season 3 Episode 14

The second of a two-parter, this episode isn't told in the usual manner, but as a Ken Burns Civil War parody, the story of Troy and Abed's falling out as they build a pillow and a blanket fort in the college begins a war for each side throughout. Sepia-toned war planning photos, Britta's terrible journalism, Annie and Jeff's text messages read as letters to home, side characters given high ranking roles, it's an entirely odd episode and one that deals with the show's most lovable duo in their darkest hour. No doubt a more divisive episode, you're either with its structure and style or not interested at all, but for a show to take away every spot of its usual function and replace it with this grand storytelling device, still landing as many jokes as any other episode, is impressive, and the core story of two manchildren feuding because they care about one another so much is wonderfully done.

Digital Estate Planning - Season 3 Episode 20

If you're in the market for a villain for a show, why not call Giancarlo Esposito? Gustavo Fring was a truly scary baddie in Breaking Bad, and he's done nasty stuff in Revolution too, so naturally a geeky show like Community found a way to bring him to the study group. But not in any usual way, the show decided to put the characters into a computer game, a 16-bit style game, where they had to fight hippies and worryingly racist Jive Turkies to get the money from Pierce's father in his will. Pierce is a technological wreck, Abed naturally finds a way to turn the world into a mode for his own imagination, whilst Troy, Jeff, Annie, Britta and Shirley try to band together to support Pierce, whilst having fun inside the world of the videogame. A truly nostalgic lovefest to old games by a gang who know what nerdiness is, and it has been embraced by the nerd community, as it has its own subreddit for programmers making a version of the game from the show. It's another layer of nerdy.

Economics Of Marine Biology - Season 4 Episode 7

Half-way through the fourth season, Community stopped going silly for a little bit and took a turn into more sitcomish tropes, and in this episode a rich lazy guy is looking to find a new college, and the Dean wants the entirety of Greendale to bend to the will of this idiot, and Annie seems to be on-board. Meanwhile, Pierce is being given time by Jeff so he's not distracted as the other rich guy at Greendale. Abed, also, is setting up his own fraternity, and every so often nods to Animal House are thrown in once more. Things get outlandish, but the heart of the story lies in Pierce and Jeff spending quality time together, and Jeff beginning to truly respect Pierce. The butt of the joke most of the time, it's lovely to see Pierce be treated with some respect, and not be a huge ass himself. In season 4 of a show, to really focus on characters and not betray what we already know is tough, and to make it funny at the same time shows how Community still has spark.

Basic Human Anatomy - Season 4 Episode 11

Jim Rash, Oscar winner for co-writing The Descendants, writes his first episode of Community, which sees Abed and Troy body-swap when they plan to watch a chunk of body-swap comedies, and AbedTroy (Troy in Abed's body) has to discuss Troy's relationship with Britta, whilst TroyAbed (Abed in Troy's body) spouts out pop culture references and tries to find how to reverse the curse with Jeff in tow. Dean Pelton finds out about this, and uses it as an excuse to try and become Jeff, which leads to some of the best acting from Jim Rash in the entire show. It's convoluted silliness and high-concept fun, but ultimately it deals with Troy and Britta's relationship, one that was cottoned onto by fans years prior but started not to work during season 4, so they found ways to make them friends and not lovers anymore. There's a sadness to the realisation that the two manchildren should really learn to grow up, because the fun they have is infectious, but they do also have responsibilities beyond themselves now, the study group and their Community. From where they were in the first season to where they are by the end of season 4, it's been a great journey, with more to come as season 5 begins airing in the US in January.

For now you can catch up with the story so far on DVD from Sony Home Entertainment from October 28th.
