It’s Always Sunny in Philadelphia

This pretty-much always funny FX series about the idiot proprietors of a very unhygienic Irish pub has covered a gamut of topics that make people uncomfortable, from race to abuse to religion to child beauty pageants. What other sitcom staged a (fake) baby funeral?

Audiences can’t get enough: It’s the longest-running live-action sitcom on television, after recently surpassing The Adventures of Ozzie & Harriet.
