Tina Fey Calls Paris Hilton a "piece of sh*t"

The actor/writer/producer who proclaimed "bitch is the new black" went on Howard Stern and told tales of Paris Hilton's visit to the SNL set.  Absolutely hysterical. In addition to calling Paris a "piece of shit", she does a dead on imitation of her and reveals the behind the scenes bet the whole cast had about the celebutante, while Stern's whole crew laughs.
