Alec Baldwin was on the 'Late Show with David Letterman' last night and before he got to discussing his run-in with the paparazzi, he talked a little bit about his recent weight loss. The side effect, as he says, is that none of his clothes fit him anymore. A fact he demonstrated by standing up and pulling his pants down to his ankles.

Sure it was a hot day in New York City yesterday, but no one expects people to just pull their pants down. But that's exactly what the hirsute '30 Rock' star did on stage at the Ed Sullivan theater. And it wasn't long before host David Letterman got in on the act too (much to Baldwin's delight who was howling with laughter).

As for the paparazzi incident, Baldwin admits he married his longtime girlfriend and of the scuffle says:

Nobody got punched. I think if I had punched him, I'd be in jail by now. I pushed him out of the way because he almost hit me in the face with his camera...

Baldwin did not address his subsequent tweets that compared the incident to the Trayvon Martin tragedy.
