'Daily Show' Pays Tribute to Longtime Writer on Last Day (Video)
Also on the late-night shows, Mark Ruffalo talks "Avengers 2," and "Transformers: Age of Extinction" actress Nicola Peltz dishes on Mark Wahlberg's real-life entourage.
The Daily Show said goodbye to its longest-serving writer Thursday.
"I've done 2,400, 2,500 of these things. We've got a writer who has done 2,800, 2,900 of them," Stewart said of J.R. Havlan, who had been with the show since its 1996 premiere. "He has — like the show — evolved. Grown from a comic-turned-writer into an accomplished writer with just a lovely wife and family."
Stewart sent Havlan off with a personalized Moment of Zen, dating back to when the writer appeared on Craig Kilborn's version of the show.
Over on CBS, Mark Ruffalo told David Letterman why playing the Hulk is the easiest gig an Avenger can have: "I don't have to work out."
Jimmy Kimmel thanked guest Bob Newhart for saving his life. "I owe you a debt of gratitude. I might not be alive if it weren't for The Bob Newhart Show.
"There is a scene in one of your episodes where you invite a guy outside and then you shut the door, and I thought it was so funny.… There was an incident in high school where a guy was very angry and I locked the door behind him" and avoided a fight, he explained.
Transformers: Age of Extinction actress Nicola Peltz recalled a crazy story of Mark Walhberg's real-life entourage, or "camp," as they call it. Two guys eat things on dares. For $200 in Shanghai one of them downed something quite shocking (watch the video to find out what it was).
