Wanda Sykes can be devastatingly funny. An Emmy Award-winning writer and comedian, Sykes is a regular on HBO's Curb Your Enthusiasm and Inside the NFL -- and also on Crank Yankers, a Comedy Central offering that features puppets acting out nasty, real-life crank calls made by a stable of comics. As Wanda Murphy, Sykes called up a tow-truck operator and hollered, "There's a turd in the backseat of my car!" Her incredulous target was so amazed that he had to get his friend on the phone, too, and the two men were soon laughing so hard they could barely talk. Sykes did it all with just her voice -- a honking, squawking, outraged bray, the acid essence of indignation applied to a poop joke.
