Making heavy use of meta-humor, chock-full of pop culture references (usually courtesy of Abed Nadir), parodying various tropes and cliches, and paying homage to genres and specific works of fiction, Community is a love letter to TV shows and movies that inspired it. Often cited as one of the best TV shows of all times, Community is one of those shows we can never get enough of (#sixseasonsandamovie).

Community may have ended (#sixseasonsandamovie) but its legacy is tremendous: tons of outstanding episodes, more memorable moments, jokes, and running gags than you can count, and, of course, plenty of awesome guest stars. Before we reveal our picks, here are some honorable mentions: Jason Alexander, Anthony Michael Hall, Taran Killam, and everyone else who didn't make the cut.

Jack Black

Community Jack Black

In "Investigative Journalism", the study group comes back from break only to find a new member has inserted himself into the group. Portrayed by Jack Black, Buddy Austin, who was in the Spanish class all semester even though no one remembers him, does his best to fit in without upsetting the natural...

...Rhythm. He even finds a role for himself as the chubby, agile guy the group lacks. There’s something inexplicably satisfying about watching Jack Black desperately try and hilariously fail to charm the study group into letting him become a member. The cringe comedy abounds as Buddy's feeble attempts at improvising songs, making puns laced with sexual innuendo, and coming up with new ideas for the group like saying "you go, girl" fall flat with the group.

Giancarlo Esposito

Community Giancarlo Esposito

In the unconventional, brilliant, and hilarious season three episode titled “Digital Estate Planning”, the study group must band together to help Pierce win in a video game so that he can claim his inheritance. They enter the game and the episode becomes an 8-bit video game for the most part. But, winning the game proves harder than any of them expected when the executor of Cornelius’s will Gilbert Lawson, portrayed by Giancarlo Esposito, joins the game in order to thwart their efforts.

Gilbert uses cheat codes to grant himself extraordinary powers in order to beat the study group to the inheritance because, as it turns out, he’s Cornelius’s son too and feels that he’s earned it more than Pierce. But despite the rocky start, the two brothers walk out of the game room in an embrace.

Travis Schuldt

Community Travis Schuldt

When Subway opens up a restaurant at Greendale, Greendale’s by-laws force the company to have their corpo-humanoid representative enroll. Travis Schuldt portrays the spokesperson named Subway, who literally becomes the product he endorses. He and Britta start an utterly ridiculous, forbidden relationship after bonding over Orwell's Nineteen Eighty-Four, thus foreshadowing that the episode will parody the book. Ultimately, Subway gets kicked out of Greendale due to his illicit affair with Britta.

In season six, Rick returns to Greendale as a Honda representative, hooks up with Britta gain, gets her to join Honda, and gets Dean Pelton, or as Rick likes to call him a “Level Seven Susceptible”, to buy practically everything Honda is selling. But Rick’s tendency to use every conceivable opportunity to shill Honda products gets in the way of his relationship with Britta, who ends up brokenhearted once again.

Rob Corddry

Community Rob Corrdry

In season two episode “Accounting for Lawyers”, we get a glimpse into what Jeff’s life used to be as a hotshot lawyer before he ended up at Greendale. The episode guest-stars Rob Corddry as Alan Connor, a lawyer from the firm Jeff used to work for. Alan is not a good person, and he's perceived by the group as a bad influence on Jeff (so much so that Abed references the movie Bad Influence).

But Corddry excels at portraying scumbags. Alan Connor is a horrible human being, but he’s also a funny character because Corddry can pull it off. In “Introduction to Finality”, he was especially villainous and even then it was hard to completely hate him.

Brie Larson

Community Brie Larson

In season four, Community lost its creator Don Harmon and experienced a dip in quality and ratings. However, that is not to say that nothing good came out of it. Dan Harmon himself has stated that the character of Rachel, portrayed by Brie Larson, is one of the few positive elements the season introduced.

Rachel made her first appearance in “Herstory of Dance”, as the coat check girl at the Sophie B. Hawkins party where she met Abed who was doing the “two dates to a dance” trope. Rachel figured him out and decided to help him. She was smart, funny, quirky and just the kind of girl you'd imagine Abed falling for. Unsurprisingly, they hit it off and went on a date. Rachel then came back in season five as Abed's girlfriend, and Jeff dubbed them "the aww couple" because they were so darn cute.

Tony Hale

Community Tony Hale

At Greendale Community College the professors are just as crazy as the students. In the late season one episode “Beginner Pottery”, the group signs up for Jeff Winger’s ultimate blow-off class Beginner Pottery, thought by Professor Holly, portrayed by the hilarious Tony Hale. Holly informs the class right off the bat that he will not tolerate any re-enacting of the pottery scene from Ghost.

Of course, by the end of the episode, someone does indeed re-enact the scene in question and that someone is Jeff. Upset that a handsome doctor is better at pottery than him, thus getting all the female attention, Jeff goes to extreme lengths to prove he's an advanced pottery student which results in so-called "Ghosting". Jeff gets thrown out of the class, but as he leaves he starts singing the Righteous Brothers song causing Holly to come at him with everything he's got.

John Goodman

Dean Laybourne intimidates Dean Pelton

In season three, we learned that the Greendale Community College had an annex: The Air Conditioning Repair School run by Greendale’s Vice Dean Robert Laybourne. Portrayed by the Roseanne star John Goodman, Laybourne was an intimidating and intense man who ruled his school with an iron fist. The most fascinating thing about the school and Laybourne is that it functioned as a secret society with Laybourne as their great leader.

In “Advanced Gay”, Laybourne discovered Troy's talents and had his henchmen capture him and other students for a private audition. Troy refused to join the A/C Repair School, which asked him to cut ties with his friends forever. Of course, this didn't stop Laybourne from coming after Troy in future episodes.

Josh Holloway

Community Josh Holloway

Community’s traditional paintball episodes are some of the best the show has to offer, and the season two two-part finale is no exception. In a “spaghetti western” parody, the first episode “A Fistful of Paintballs”, we find the school has been turned into a wild west battleground and the members of the study group have been divided. In this episode, we meet the mysterious gunslinger, The Black Rider, portrayed by Lost’s Josh Holloway.

The network TV good-looking Holloway turns Annie into a lovelorn teenager, causes Jeff to question his status as the most handsome guy on campus, and gets in some hilarious zingers. It is later revealed that The Black Rider entered the tournament as a gun-for-hire sent by City College’s Dean Speck to prevent anyone from Greendale from winning the prize money.

Mitch Hurwitz

Community Mitch Hurwitz

Greendale Community College is populated mostly by offbeat, social outcasts. One of the school’s most popular weirdos is Preston Koogler, the middle-aged student who lives in a state of arrested development. The perpetual adolescent, portrayed by Arrested Development creator Mitch Hurwitz, is the stereotypical college student.

Koogler made his first appearance in season five episode “App Development and Condiments”, where the beta testing of the social app “MeowMeowBeenz” led to the creation of a social caste system imposed by the “Fives”, which Koogler was a part of. Mitch Hurwitz delivered tons of laughs and proved he’s a real scene-stealer. The end tag shows a trailer for “Koogler” an R-rated 1980s teen college movie, which sadly isn't real. But Koogler makes a hilarious comeback in "Modern Warfare" as a paintball munitions supplier named "Fun Dad".

Levar Burton

Community LeVar Burton

LeVar Burton, best known for portraying Geordi LaForge on Star Trek: The Next Generation and hosting the PBS children series Reading Rainbow, appeared on two Community episodes as himself. Burton made his first guest appearance in season two, “Intermediate Documentary Filmmaking”, where Pierce pretends to be dying to bequeath cryptic and mean gifts on the study group.

His gift to Troy: the chance to meet his hero – LeVar Burton. However, Troy sees it more like a curse than a gift as he’s too afraid to even look at Burton, which led to some pretty hilarious interactions between the two. Troy's wide-eyed face alone is enough to make this one of our favorite Community moments. Burton pops up again in “Geothermal Escapism” as Troy's co-captain on his voyage.
