I first fell in LOVE with Sarah Silverman after seeing her roll-on-the-floor funny show Jesus Is Magic where at moments you could feel the tension in the audience form her off-the-cuff racist remarks and feigned biggotry. She has since moved on to having a very sucessful Comedy Central show "The Sarah Silverman Program" - where she still plays the part, but without a lot of the racist undertones. And FYI - I'm not a racist, so thats not what I love about her per se.
I guess what I love about her comedy is it makes you think. It's all very coordinated, her character, her songs, her stereotypes, her mouth. What she is really doing is getting a reaction and showing us how funny actual bigots are. I just love her.
I am bringing this all up I guess because I just found some clips from her show on itunes - under the comedy central podcast. She has been in my mind and my pocket all day. Check her out - its FREE! And if you like her - definitely check out "Jesus Is Magic" (can also be DLed on itunes - but for a fee) or "The Sarah Silverman Program" on Comedy Central!
