Remember when Donald Trump tried to “out” Jon Stewart’s Jewish heritage in 2013?

In 2013, Donald Trump had quite the burn for political satirist and former Daily Show host Jon Stewart: He called him by his birth name, Jonathan Leibowitz.

It was payback. Stewart had called Trump a "boiled ham with a wig" on The Daily Show, and in retaliation Trump seemingly tried to either shame Stewart for hiding his Jewish heritage or for being Jewish altogether — the motives are unclear. It's important to note that in addition to the general prevalence of stage names, Stewart has also never hidden his Jewish heritage.

When Trump "outed" him, Stewart had the perfect comeback — equally as childish, and with a Daily Show–esque bite to it — exposing Trump's real name: Fuckface Von Clownstick.

"LexisNexis will tell you that, and we wanted to know why he was running away from the Von Clownstick heritage," Stewart joked earlier this May, three years after the incident, as a guest on David Axelrod's podcast, The Axe Files.

Three years later, Stewart still had the perfect comeback for Trump, calling the presumptive Republican nominee a "man-baby."

"I don't even know if Donald Trump is eligible to run for president," Stewart joked on The Axe Files. "This isn't a birther thing. Are you eligible to run for president if you are a man-baby? He has the physical countenance of a man and a baby's temperament and hands."

Character is destiny, Stewart said, and he finds Trump to be "the most thin-skinned individual" — much more than the average politician.

"I don't know that a man-baby can be president."

It's no surprise that Stewart, who has long been a Trump critic, had some choice words for the presumptive Republican presidential nominee. Their petty Twitter fight from 2013 proves Trump doesn't have the resolve for the White House, he says.

"As you know, great leaders tweet," Stewart said. "In fact, I remember Lincoln's Gettysburg tweetstorm. ... After the Gettysburg Address, he tweeted out, 'Emancipate this, motherfucker.'"

Watch: Why the Daily Show had to change

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
