VIDEO: David Letterman & Jimmy Kimmel Share Laugh At Jay Leno's Expense

David Letterman and talk show rival Jimmy Kimmel shared a laugh at Jay Leno's expense on The Late Show Tuesday, and RadarOnline.com has all the highlights.

Both men, you’ll remember, criticized Leno for his actions during the January shakeup at NBC -- and still seem to have plenty left to say about their late night colleague.

Kimmel, who did an entire show dressed up as Leno, said, "It's fun to be Jay -- it's easier. You should try it."

Kimmel told Letterman that Leno called him after that show and told him he liked it, then invited him to do his 10 at 10 bit, where things took a turn for the ugly.

"He asked me 10 questions about nothing and I asked him 10 questions about him stealing Conan's job from him," Kimmel said.

Letterman said the late night shakeup "was fun -- it was funny and nobody got hurt.

"The only people who got hurt was NBC," Letterman said. "They lost hundreds of millions of dollars. We don't care about NBC. I mean, Jay didn't get hurt, you didn't get hurt, Conan didn't get hurt, I certainly didn't get hurt and it was just a lot of fun."
