Imagine having Cher on your outgoing voicemail message asking your friends to leave a message after the tone, ending with her signature “WOAH!” Personally, I would die. For the low price of $299, the “Woman’s World” singer will do just that.

The advocacy group Autism Speaks has corralled several celebrities including Bryan Cranston, Adam West, Jack Black, Peter Dinklage, Jim Parsons, Mark Hamill, Zachary Quinto, Michael Dorn and Vin Scully to name a few to record a 20-second-long customized message all for the sake of charity.

From Oct. 7 to Oct. 13, a limited number of MP3 messages you write will be recorded by each celebrity on a first-come, first-served basis for fans to do with as they wish. Naturally, all requests must be of the PG nature. So don’t expect Quinto to record sweet dirty nothings on your voicemail. I’m sure he’d do it for free if you’re his type ;)

Last year’s effort which featured Betty White, Will Ferrell and Patrick Stewart to name a few recorded about 342 messages, raising roughly $100,000. The initiative is the brainchild of Ed Asner (The Mary Tyler Show) and his son Matt who works for Autism Speaks. Check out a few of the recordings from last year below.
