i signed on to this forum to find a certain comedian. she appeared on david letterman recently and was talking about her show (sitcom) which stars her as herself and her sister. it's not on any of the big three networks. that's about all i have to go on. i've searched the letterman databases and have come up empty. does his sound familiar to anybody?

thanks in advance.

I could be off, but I'm 95% sure it's Sarah Silverman, and the show is called "The Sarah Silverman Program"
