Former Saturday Night Live star and head writer Tina Fey has slammed Paris Hilton for being a horrible guest host on the comedy sketch show. Fey appeared on the raunchy Howard Stern radio show Thursday morning (16NOV06), where she explained that guest hosts are usually great, but once every few years you get a bad one, like Hilton, who was "a piece of s**t!" According to, Fey was less than impressed with Hilton, claiming she had "the hair of a Fraggle (a muppet-like character from FRAGGLE ROCK) and left "nasty wads of Barbie hair on the floor" from her "cheap weave". She also revealed that the socialite asked the writers to pen a skit so she could play Jessica Simpson "because I hate her" and "she's fat".
