Funnyman Larry David is auctioning 20 minutes of his time to raise money for Michael J. Fox's charity.

The highest bidder will win a 20-minute one-on-one 'pitch meeting' to discuss ideas with the Seinfeld co-creator in his office in Santa Monica, California.

The Charity Buzz auction is expected to raise $5,000 for the Michael J. Fox Foundation for Parkinson's Research.

Fox, who was diagnosed with the degenerative disorder in 1991, played his Parkinson's disease for laughs with a cameo role in an episode of David's sitcom Curb Your Enthusiasm that aired on Sunday.
