See... I know my shit. Umm... I can't think of anyone right now, but I have a shitty memory. If I remember anyone else I will let you know.

Jimmy Norton is pretty funny. He is from the Opie and Anthony show on XM 202 (shamless plug for a radio show I love.)

Here is a clip of him on leno.

He is a very dirty comic so this is like the clean version.
