Earlier this month, 14-year-old Jack Aiello delivered his eighth grade graduation speech as Donald Trump, along with sections as Hillary Clinton, Ted Cruz, Barack Obama, and finally, Bernie Sanders. And 2.2 million YouTube views later, the Chicago teen was standing side by side with Jimmy Fallon’s Donald Trump on The Tonight Show.

Wednesday night’s sketch opened with Fallon as Trump at the podium, preparing to make a “very big announcement” about his running mate. After dismissing Chris Christie, LeBron James, and Chewbacca Mom, Trump declared that the “only person good enough to be my vice president is me.”

As Fallon’s Trump put it, 14 years ago, he created a clone of himself, introducing “your next vice president, Little Donald.” At that point, Aiello emerged in full Trump regalia, pointing out that he and adult Donald have “the same size hands.”

At Fallon’s request, Little Donald prank-called Clinton as Sanders—“Is your refrigerator running? Well, so am I! And I am never, ever dropping out”—and did the same to Sanders as Clinton—“I was going to email you, but before I pressed send, I accidentally deleted it.” Asked where he learned to do such great impressions, Little Donald replied, “Trump University, which is terrific, by the way.”

If the real Trump does somehow manage to get elected president, Aiello should be ready to take over for Darrell Hammond on Saturday Night Live by the time he’s ready to run against Kanye West in 2020.
