Watch Arlington Heights Student Impressionist Backstage at 'The Tonight Show' (VIDEO)

It's been quite the summer for Jack Aiello. And it's still only June.

Earlier this month, the Arlington Heights high school-freshman-to-be made an internet name for himself after the video of his witty eighth-grade graduation speech that featured an impressive array of political impressions spread across YouTube, gaining more than 2.2 million views and counting.

On Wednesday, Jack and his impersonations of presidential candidates received even more exposure when he appeared on The Tonight Show Starring Jimmy Fallon.

And Jack wasn't just a guest. He also had the distinction of performing a sketch with Fallon, pitting his Trump impression—as Little Donald, the presumptive Republican candidate's running mate—against the talk show host's impersonation.

Jack also was interviewed backstage at The Tonight Show, and here were some of the highlights:

• To perfect his impressions, Jack watched the debates and studied the candidates. "They all have very unique and distinct mannerisms," he said.
• It took him a month to perfect his speech, and the final version was very different from what he eventually delivered.
• How would he describe his experience on The Tonight Show? "It's so cool to have been on the show. I really enjoyed that."
