During an appearance Friday on CBS' Late Night, CNN anchor Anderson Cooper told David Letterman that he prefers to be called “light in the loafers” rather than homosexual.

The 45-year-old Cooper announced he's gay last year after ducking rumors about his sexual orientation for years.

On Late Night, Letterman attempted a two-stage fist bump with Anderson, who after bungling the bump pulled back his hand and said, “Hey, I'm gay. We don't do this kind of thing. I don't know, I don't know. That's making me nervous.”

“I wish I had a nickle for every time I heard that in my life, 'Dave I'm gay, we don't do this kind of thing,'” Letterman joked.

Letterman then got serious, asking, “This is interesting to me. You made it be known, beyond your immediate family and friends, that you're a homosexual. And why at this point in your life ...”

“We prefer the term light in the loafers,” Cooper interrupted. (The video is embedded on this page. Visit our video library for more videos.)
