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.
