After what felt like the world’s longest hiatus, we couldn’t be more pumped about the big return of the Paddy’s Pub gang in It's Always Sunny In Philadelphia—there are only so many times you can watch the same five episodes on Hulu without wanting to bust your computer. Over the past six seasons, the dark comedy’s become notorious for its embracing of taboo themes, making us guffaw at otherwise uncomfortable topics like pedophiles, racism, disabilities, and more.

However, just when you think that Mac (Rob McElhenney), Dee (Kaitlin Olson), Dennis (Glenn Howerton), Charlie (Charlie Day), and Frank (Danny DeVito) have pretty much broached all things un-PC, that’s exactly when the show breaks new ground by having one of the characters launch a protest against gay marriage, or get upset over being mistaken for a *fat* sex offender.

With the seventh season premiering tonight on FX, we can only imagine the new highs (or lows) in untouchable subject matter the series might reach, which is why we at Complex have decided to share our best educated guesses with you. In honor of the show’s return, check out our list of 10 Taboo Subjects That It’s Always Sunny in Philadelphia Hasn’t Touched On Yet.
