Alec Baldwin, who had a run-in on Tuesday with a photographer, stopped by “Late Show with David Letterman” on Wednesdsay, and no sooner did he step onstage did all mayhem break out.

Moments after the “30 Rock” star made his way across the stage — with “Hit Me With Your Best Shot” purposely playing in the background — Baldwin referenced Letterman’s earlier “Top 10” list of “Signs You’re Not Ready For Swimsuit Season.”

Baldwin wanted to prove that he is ready for swimsuit season — having lost a lot of weight — by dropping his pants.

But that’s not where it ended.

Letterman then interjected, “Now I’m think should I take my pants off,” and with that the talk-show host also dropped trou.

There’s more, including Letterman talking about his “junk,” but just watch the video.
