Alec Baldwin Lets It All Hang Out on “The Late Show"

Alec made reference to Letterman’s “Top 10 Signs Your Not Ready for Swimsuit Season” segment by noting that he’d lost so much weight his pants wouldn’t stay up.

And then Mr. Baldwin proceeded to put his hands in his pockets and push his trousers down, revealing his legs and undergarments.

From there, Letterman questioned, “Now I’m thinking should I take my pants off?” before swiftly dropping his own trousers to the floor and worrying out loud if anyone saw his “junk.”
