We just can't get enough of Sarah Silverman. First she lent her talent to the Burma: It Can't Wait campaign, using her humor to bring awareness to a vicious regime in a way that only Sarah could.

Then she made the best entrance ever at the NYC Costume Gala Monday night.

And on Friday the lovely Sarah is doing stand-up for a cause at Columbia University.

"Project ALS is a vital crusade - to find a cure for a horrific disease," Sarah said, "and also to fight for the legality of stem cell research - for the right to put science over fundamentalism so that people may live past this and countless other diseases."

Bravo to Sarah for giving her name and time to Project ALS, making a stand on both a political and health issue.

We can't wait to see Sarah perform. You can get tickets here to support Project ALS.
