Is there something in the water at NBC that gives its TV talent restless leg?

MSNBC's Chris Matthews is the latest journo to bust a move, on the March 19 "Ellen DeGeneres" show.

Looks like colleague David Gregory has some fresh competition, but I'm confident the NBC White House correspondent has what it takes. After all, he can get down to anything from Hilary Duff to Mary J. Blige.
