When 10 @ 10 Goes Wrong: Jimmy Kimmel Roasts Jay Leno On His Own Show!

I'm not sure what Jay Leno was thinking when he brought Jimmy Kimmel to do 10 at 10 on his show, especially after Kimmel recently impersonated Leno on Jimmy Kimmel Live.

The clip is funny, but tough to watch as Kimmel expertly slices and dices Leno to late night shreds:

Leno: "What’s the best prank Kimmel ever pulled?"

Kimmel: “I told a guy that five years from now, I’m gonna give you my show. And then when the five years came, I gave it to him, and then I took it back almost instantly,”
