Guys never really outgrow that, "wanna wrestle?" stage, do they? Even two grown men like Jimmy Fallon and Stephen Colbert, both on their A-game with successful talk shows.

That's why it should come as no surprise when the two used their 30-second elevator ride to wrestle each other to the ground after 'Late Night with Jimmy Fallon' (weeknights, 12:35AM on NBC). No harm done, right? A little cardio action. All in good fun. Wait ... is this part of the late night wars?

The Internet is still abuzzin' over the Super Bowl commercial with Jay Leno, Oprah Winfrey and David Letterman. Leno talked about it on 'The Jay Leno Show' (weeknights, 10PM on NBC), and says he flew to New York City in complete secrecy to shoot the spot. He even disguised himself to get into Letterman's studio (which must have been a blast for Leno!), so none of their staff knew anything about the taping.

But the best part? Any animosity between Leno and Letterman seems to be a thing of the past. "I walk in, I see Dave, he puts his hand out and I shake hands, and you know, whatever happened over the past 18 years, disappeared," said Leno. "It was great to see my old friend again." All together now -- Awwwww! What a sweet little Valentine's story between old friends. Group hug.
