Jimmy Kimmel Publicly Pounds Leno on Leno's Show

I've been offline all day and out of the loop. As I catch up on what I've missed, I see Jimmy Kimmel appeared on Jay Leno's show and totally bitch slapped him.

Leno doesn't seem to realize he's being publicly pounded on his own show. What happened to NIMBYism?

Very well played, Mr. Kimmel...
