The long-running TV comedy series, “It’s Always Sunny in Philadelphia,” returns Wednesday, July 9 at 9 p.m. ET on FXX.

Some teachers walk into a bar…and meet one of television's most iconic comedic gangs. It sounds like the setup to a bad joke, but it's a taste of what viewers will get when they return to Paddy's Pub for It's Always Sunny in Philadelphia's 17th-season opener.

Season 17, Episode 1 of FX's "It's Always Sunny in Philadelphia," marks part two of its crossover event with ABC's "Abbott Elementary."
