Hey, did you know that you can say that something “sucks balls” on television? Yeah, we didn’t know that. It was left to Louis C.K. to break that new ground last night with his Late Show appearance to promote the upcoming season of Louie. (That’s the one debuting this coming Monday on FX, with guest star Yvonne Strahovski.) We remember way back when Woody Harrelson said that he was “pissed” about something, and then pondered if you can say “pissed” on television–and it turns out that you could, but we didn’t know that back then, either. We’ve forgotten just how educational The Late Show has been over the years. Anyway, enjoy the video, which starts with Louie being nicely self-deprecating about having to endure running everything with his own show. It ends with him saying “sucks balls,” but we’ve already given away that spoiler.
