Letterman, Dr. Phil Talk Late-Night WarsThe late-night wars are pretty much over -- or at least on summer vacation until Conan O'Brien's show debuts this fall on TBS. Things have settled down, and yet David Letterman still can't resist throwing a few belated spitballs at Jay Leno.

Maybe you got a rueful chuckle out of the moment on Monday night's 'Late Show' when Letterman, talking to guest Dr. Phil McGraw, started making fun of Leno again, doing a squeaky-voiced imitation of the 'Tonight Show' host and calling him "a complete boob." But maybe you also thought, "C'mon, Dave, enough already."
