Larry David pushes the boundaries of comedy more than usual in a new season episode of "Curb Your Enthusiasm." With the help of Michael J. Fox, who will play himself, the show pokes fun at Parkinson's disease.
Fox, who has lived with Parkinson's disease since 1991, told TV Guide that the episode has Larry David believing that "I'm being symptomatic just to annoy him -- a whole passive-aggressive thing. He's complaining because I'm shuffling and making noise upstairs. It's very funny."
