Austim Speaks contest: Get a star to record a message on your voicemail!
Have Derek Jeter record a voicemail for your brother.
Have William Shatner or Patrick Stewart or Leonard Nimoy record a message for that Star Trek-lover in your family.
Have Will Ferrell say something hysterical on your home machine.
All of these are possible if you donate $299 t Autism Speaks between Dec. 3 and Dec. 9 - on a first-come, first-served basis.
The messages can be up to 20 seconds and they'll be MP3 messages so you can do whatever you want with them. PG only, folks!
Others to choose from: Betty White, Ed Asner, Carrie Fisher, Tom Hanks, Morgan Freeman
