It’s a social media showdown! President Barack Obama appeared on Jimmy Kimmel Live! on Monday, October 24, and took the opportunity to troll Donald Trump during the famous "Mean Tweets" sketch. Hear his hilarious zinger in the clip above!

POTUS was a good sport as he read out a long list of insults people had posted about him, from mocking his ugly dad jeans, to being branded “the Nickelback of presidents,” but he saved the best for last.

Obama read out a tweet Trump himself had written about him: “President Obama will go down as perhaps the worst president in the history of the United States!”

But his comeback was priceless: “Well, @realdonaldtrump, at least I will go down as a president.”

The 55-year-old then dropped the mic, to a round of applause from the audience.

Although he joked during the hilarious sketch, he got serious when he sat down for a chat with the host to talk about the controversial election.

He hinted that he feared for the future of the country if Trump, 70, is elected and spoke about why he and his wife, Michelle Obama, are backing Hillary Clinton, 68.

"We joke about Trump, but I do think part of the reason you’ve seen Michelle passionate in this election, part of the reason we get involved is not just because Hillary’s going to be a great president, but it’s also because there’s something different about the way Trump has operated in the political sphere,” he said. “I ran against McCain, against Romney. I thought I could do a better job, but they’re both honorable men. And if they won, I wouldn’t worry about generally the course of the country."

Kimmel asked if Obama would have considered running again if it was legal.

“If I were able to run for a third term, Michelle would divorce me. So it’s useful that I don’t have that choice to make.”

He added: “All the women in my life are looking forward to being able to live a more normal life.”
