Joy and Regis Philbin are so adorable together. They're just a hoot every time we see them together on a show, and they didn't disappoint on 'Late Show With David Letterman' (weeknights, 11:35PM ET on CBS).

Throw in Letterman dishing on the Super Bowl commercial, Regis accidentally calling him 'Jay,' and Joy saying that Regis is starting to lose it, and it's just good fun. Not only that, she's a knock-out!
