Celebrities Remember David Letterman's Best 'Late Show' Moments (Video)

David Letterman‘s final The Late Show is coming up on Wednesday (April 20), and celebrities are remembering some of his best moments, compiled by GQ!

Will Ferrell, Tina Fey, Jimmy Kimmel, Sarah Silverman, Ricky Gervais, Paul Rudd and more remembered the 68-year-old talk show host’s funniest moments.

Tina, who has made 19 appearances on the show, said of her favorite moment: “The first thing that comes to mind is his epic interview of Paris Hilton after she got out of jail. Just a masterful dismantling of a phony. For my generation, Dave completely defined the way we spoke to each other. I didn’t meet one boy in college who wasn’t talking in Dave‘s cadence and ripping off his style. Whose deal will young people adopt now to try to impress each other? I worry for them.”

B.J. Novak: “Rod Blagojevich appeared on the show one week after his impeachment for corruption. He walked out, sat down, and with a big grin said to Letterman, ‘I have to tell you, for years I have wanted to be on your show in the worst way.’ And Dave said, ‘Well, you’re on in the worst way.’ It was the quickest, smartest thing I have ever seen. My God. What a line.”

Will Forte: “Anytime he put on a jumpsuit. Like the time he wore a suit covered with Alka-Seltzer and jumped in a tank of water. The best thing is that there was always this incredibly long setup, he did the thing, and then it was just over. There was never any kind of goal at the end other than ‘We’re just doing this because we find it funny. So get on board.’ ”
