Katt Williams may not be an actual pimp, but he's made a living portraying one. He provides the voice for A Pimp Named Slickback on the Comedy Central cartoon "The Boondocks," stars in the HBO special "The Pimp Chronicles Pt. 1" and titled his debut album "It's Pimpin' Pimpin'." Williams' humor seldom surpasses the street level, and he leans on the n-word like a lamppost during his often-hilarious sets. Make sure you bring $45.50-$50.50 to the Landmark Theater Wednesday, April 16, at 8 p.m. Pimps like to be paid in a timely manner. 646-4213.
