On "The Late Show" Friday night, Stephen Colbert interrupted his monologue to scold a man for having his feet propped up on the stage. The guy was sleeping, and had his arm draped on the girl next to him.

When he woke up, it turned out to be Bill Murray. He got up to leave and asked the girl if she wanted to go with him. Then they both walked out.

It was clearly a scripted bit, but that was it. Bill wasn't there for an interview or anything, just to hang out in the audience for that joke.
