It Sucks to Work with Danny DeVito

The following video is completely NSFW, but hysterical!

According to Danny DeVito's contract for his FX show, "It's Always Sunny in Philadelphia," co-stars have to perform oral sex on him before the start of the third season. Good luck getting that thought out of your head.

Okay, it's not actually true -- it's the subject of the latest video on In the clip, Charlie learns that he is contractually bound to service DeVito -- who asks that Charlie use Vaseline on his mouth. Not only does Charlie have to go through with it, but he has to do it in front of Danny's wife, Rhea Perlman, and a certain '80s child star -- 'cause that makes it sooooo much easier.

"It's Always Sunny in Philadelphia" premieres September 13 at 10:00 PM on FX.
