Does he? Who is he? I like Kevin James. Who is his brother?

Kevin James' brother, Gary Valentine, who plays "cousin Danny" on The King Of Queens (Kevin's real name is Valentine as well) has been a consistently working stand-up comedian for about 20 years. Yes, having a popular sitcom star for a brother helps the jump to TV and movies, but he's actually been in the game longer than Kevin.

I really don't think he's terrible. I mean he's not great but there are a lot less funny people in TV and film. The other guy with the brown poofy hair on that show is a funny actor. I think he was in Lonesome Jim which I really liked.
