My biggest girl crush to date, is Sarah Silverman. She's not exactly what you would call conventionally pretty, but I am so in love with her. I'm sure her comedy and her voice make it easier for me to love her, as well. She is the cutest thing ever! I would love to go completely gay for her. I might even love her more than Amanda Blank, only because I knew of her before I knew of Amanda.
You must also watch this video. An installment of her stand up act, "Jesus is Magic". She has to be the funniest broad ever. You would think with her nasal, sweet voice, she would be all prim and proper, but she has the mouth of a fucking truck driver married to a trailer park chick!
