David Letterman To Brian Williams: Stop Going On Leno (VIDEO)

Brian Williams appeared on David Letterman's show Monday, and the late night host had just one request of his guest: stop going on Jay Leno's show.

Williams is a regular on both shows, which means he sometimes has to deal with the awkward fact that Leno, his fellow NBC host, is a bitter rival of Letterman's. On Monday's show, Letterman seemed determined not to let him forget it.

"I don't like it when you go on that show," he said.

"That's funny, because he doesn't like it when I come here," Williams replied.

"Could you not go on that show?" Letterman persisted. He also dropped into an impersonation of Leno, pointed out that it takes much less time for Williams to travel to his studio in Midtown Manhattan than to Leno's studio in Los Angeles, and mocked the idea that Leno is a blue-collar guy ("He's got 400 cars," he noted).

"I like to think of you and me as more real guys as opposed to you and Jay," Letterman concluded. "You and I are the real thing."

WATCH:

Williams treated the issue with fair and balanced aplomb, insisting that he watches both Letterman and Leno and has no favorites. Still, he was relieved when Letterman finally moved on.

"Topic 2," he said, yanking the conversation in another direction.
