List RulesVote up the episodes that are all-time great episodes of 'Always Sunny.'

It's Always Sunny in Philadelphia is officially the longest-running live-action sitcom in television history. That's pretty impressive for a show that's never won an Emmy and frequently addresses the existence of "toe knives."

There have been 14 seasons of It's Always Sunny in Philadelphia, and each one is consistently more insane than the last. The show is one of the most consistently funny shows in TV history, but even a show this good has episodes that stand out. Every season has a handful of gems that are just so funny or so absurd that they stick in your brain long after the episode has finished. 

If you had to choose just one episode from each season as "the best," which would you choose? Based on user ratings from sites like Metacritic, Rotten Tomatoes, and IMDb, these are the fan-favorite episodes of each season.

    What The Episode Is About: In an attempt to emancipate themselves from their jobs, Dennis and Dee formulate a plan to get on welfare.

    What Makes It The Best: This is the episode where the twins first get hooked on crack, and it's one of the funniest episodes of the entire series. Their crack habit still manages to catch up with them occasionally, even a decade after they first got hooked.

    Other Honorable Mentions: Technically, "Mac Bangs Dennis' Mom" has a higher score on IMDb and while it's hilarious, it doesn't have the same impact on the series as the welfare episode.

    What The Episode Is About: The Gang teaches Frank how to play their original board game, Chardee MacDennis.

    What Makes It The Best: On top of just being hysterical, this episode is a great look into the psychology of the Gang. The questions they ask, the challenges they invent, and the rules they adhere to showcase just how unstable they are. Having said that, pretty much every Sunny fan probably wants to play some version of Chardee MacDennis in real life. 

    Other Honorable Mentions: This is the "Fat Mac" season, and the whole thing is truly glorious. Highlights include "Thunder Gun Express," "Frank Reynolds' Little Beauties," "The Gang Goes to the Jersey Shore," and "Frank's Pretty Woman."

    What The Episode Is About: The Gang decides to spend a leisurely day at the water park. 

    What Makes It The Best: This is one of the highest-rated episodes of the entire series, and it's one of the pinnacles of Sunny slapstick. Mac and Dee get stuck in a water slide, Dennis gets punked by a teenage con-girl, and Frank ruins his back by sliding down a closed and dry water slide. Speaking of Frank, this is the one where he pretends to have AIDS to cut in line and creates pandemonium after his bloody back "contaminates" the entire park. 

    Other Honorable Mentions: "Hero or Hate Crime?" is another episode from this season that happens to be among the series' most highly-rated episodes.

    What The Episode Is About: After Dee introduces her rapper boyfriend to the Gang, they all begin to suspect that he may be developmentally disabled.

    What Makes It The Best: Lil' Kevin's performance is one of the funniest guest spots on the show, as you really can't tell if he's disabled or not before the end of the show. This is also the episode where the boys decide to make a band, called the Pecan Sandies or Chemical Toilet depending on whom you ask. If that isn't enough Sunny history, it's also the episode where Dennis and Charlie first write and perform the "Dayman" song. Charlie also introduces the Nightman in this episode.  

    Other Honorable Mentions: Season 3 is really where the show starts to hit its stride and start knocking episode after episode out of the park. This season contains peak episodes like "The Gang Gets Invincible," "Mac Is a Serial Killer," and "The Gang Dances Their Asses Off."
