David Letterman and Conan O'Brien Take On Jay Leno

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.
