Jon Stewart made a surprise television appearance Thursday night, and it had nothing to do with President Trump, Stephen Colbert or politics of any kind.

In fact, it was all about a Delaware County teen's bar mitzvah.

Will Rubin, a 13-year-old who lives in Media, decided to make late-night talk show host Jimmy Kimmel the focus of his ceremony, complete with a set mimicking the stage of Jimmy Kimmel Live!.

"I want your job one day," Rubin said in a video Kimmel aired on his show Thursday night. The host responded: "I don't know if that was an invitation or a threat."

Kimmel ultimately didn't attend the ceremony, noting there was "no way in hell I'm going to Media, Pennsylvania." But he did send Rubin an ice sculpture of his sidekick Guillermo's head and filmed a video message that was aired during the bar mitzvah.

"Today, you become a man with no body hair," Kimmel quipped.

"When I heard you themed your bar mitzvah after my show, I was so moved I called my attorney to see what kind of damages I could collect." Kimmel added. "But then a little voice in my head told me the optics of suing a 13-year-old on his big day might not look right, so I agree to settle for half of the money your grandparents give you tonight."

Rubin appeared on Kimmel's show Thursday night in a remote interview, and just as Kimmel was asking the Delco teen about the ceremony, a bearded stranger stumbled onto the set wearing a T-shirt and a pair of jeans.

It was Stewart.

"I'm Jon Stewart; I'm a talk show host as well – I was, years ago," Stewart told Rubin. "And I'm a Jew. You probably had your choice of idolizing any talk show host, and you could have gone with a Jew, is what I'm saying."

After asking to speak with Rubin, Stewart implored Kimmel to "sheket b'vakasha" (which translates to "be quiet please" in Hebrew). He turned back to Rubin and noted that Kimmel didn't understand the reference because he's not Jewish.

"Don't be fooled by his learned-looking beard and his puffy, sad eyes. He's not rabbinical, he's just unhealthy," Stewart added. "Will, wouldn't you rather idolize a talk show host who is also circumcised? He's not. Will, I don't know how I put this. How do the kids say this? He's still wearing his hoodie."

Kimmel then asked Rubin: "Maybe you can have a Jon Stewart themed wedding?"

"I'll think about it," the teen dryly responded.
