Jon Stewart roasts Jimmy Kimmel on his own show: 'He’s just unhealthy'

A teenager hosted a Jimmy Kimmel-themed bar mitzvah, and Jon Stewart is not happy. about it.

Will, a 13-year-old from suburban Philadelphia, made Kimmel the theme of his bar mitzvah ceremony, complete with a replica of the talk show host. To thank him, Kimmel invited Will on his show via telecast Thursday, only to have Stewart interrupt their interview by wandering onto the stage as the audience cheered.

"I'm Jon Stewart, I'm a talk show host as well, or I was a few years ago, and I'm a Jew," he joked. “You probably had your choice of idolizing any talk-show host and you could’ve gone with a Jew."

Then, Stewart moved onto berating Kimmel for several aspects of his non-Jewishness, yelling Hebrew at him and cracking circumcision jokes. 

"Don't be fooled by his learned-looking beard and his puffy, sad eyes," Stewart said about Kimmel. "He’s not rabbinical, he’s just unhealthy. Will, wouldn’t you rather idolize a talk-show host who is also circumcised?"
