Comedy Central

The Daily Show said goodbye to its longest-serving writer Thursday.

“I’ve done 2,400 (or) 2,500 of these things. We’ve got a writer who has done 2,800 (or) 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.”

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.

Jonah Hill

After a teary Tonight Show apology for making a homophobic slur, Jonah Hill was asked to say sorry for a different transgression on The Colbert Report Wednesday, when Stephen Colbert asked Hill if he wanted to address “the elephant in the room.”

“It was revealed you are friends with Adam Levine. Would you like to apologize? Because I have had ‘Moves Like Jagger’ in my head for three years, and someone needs to say their  f—ing sorry for that.”

Earlier on Comedy Central, new Daily Show correspondent Michael Che made his debut with a well-informed report from Syria that blew Jon Stewart away. So much so that Aasif Mandvi showed up to express his jealousy. 

Anderson Cooper confessed to David Letterman that he is a secret McDonald’s eater. “Once a month I allow myself the number one meal and I super size it,” he revealed, saying his last trip to the golden arches was on his birthday. “I said it was my birthday, and she looked at me like I was the loneliest and most pathetic person on the planet. Did I expect her to give me a Happy Meal?”
