David Letterman and Conan O'Brien Take On Jay Leno

It was a rare site of late night hosts together on the same show as Conan O'Brien was a guest on Late Show with David Letterman, and the topic of conversation was none other than Jay Leno. INSIDE EDITION has the scoop.

Late night rivals Conan O'Brien and Dave Letterman join forces against Jay Leno. The funnymen joked about the now famous late night shake-up that booted O'Brien, and brought back Jay Leno as host of The Tonight Show in 2010.

Letterman said, "I think the longer we just sit here, the more uncomfortable it will make Jay."

"I was delighted by everything that happened, except you losing your job," said Letterman.
