Richard Grieco is making a fool of himself - on purpose.

The former TV star of "21 Jump Street" and "Booker" was cast as himself - sort of - in the new Amy Heckerling film "A Night at the Roxbury.""I play a caricature of myself," Grieco says in the September issue of Cosmopolitan. "I wear my hair really big, and I have an earring, a tight chain around my neck, the leather jacket and pants - bigger than life."

Out of the limelight for several years, Grieco is trying to resurrect his acting career.
