After about 02:33 in the November 8, 2017 video Bill Murray and Jimmy Kimmel on David Letterman's Specialness Murray says:
(Bill:)... You know that that was the fun part of it and he, and in the early days it was fun to... you really had to be on, you really had to be rolling and you had to come in with one in the chamber, you couldn't come in cold and because you've seen him just, like I was talking about last night, that he would just cut people—kill people—if they were bad or vain which was where the fatal flaw, he would just say "Jimmy Kimmel, ladies and gentlemen, thanks for coming." And that was it. It went to the commercial and like that this person just got one minute 15 seconds and they're gone, he just kicks 'em.
(Jimmy:) I felt a weird... when I watched the show, I'd decide which celebrities I thought were we're good and which were bad based on Dave's reaction to them, and know when I was on the show the first time I felt I had to apply that standard, it's me, you know, and and if he didn't like me then I was I was forced to be in that group with Shirley MacLaine or whoever the hell was in that group, and so it was really for me a test—it could have potentially ruined my whole life.
Question: Which guests did David Letterman get rid of the quickest? Was Shirley MacLaine really one of them?
