World leaders openly laughed at President Donald Trump as he boasted of his accomplishments during his United Nations speech on Tuesday.

And Twitter users are joining in with jeers of their own.

Many pointed to an old slam Trump directed at President Barack Obama that isn’t aging well:

We need a President who isn't a laughing stock to the entire World. We need a truly great leader, a genius at strategy and winning. Respect! — Donald J. Trump (@realDonaldTrump) August 9, 2014

Trump later claimed he meant to make his fellow leaders laugh.

However, it’s not the only time Trump made such a comment, as Stephen Colbert’s “Late Show” pointed out:

Trump promised that if he became President, the world would no longer be laughing at the U.S.

The irony of the world laughing at Trump after years of those kinds of remarks wasn’t lost on Twitter users:

We're splitting our guts! As is the world. The devil, they say, hates nothing more than being laughed at. — BW (@BeHereNow183) September 26, 2018

Feel like the UN audience is on to something by laughing at Trump - he was clearly embarassed. Maybe we should all just laugh every time he speaks? Reporters, audience members, everyone. Start a cackling wave & shame him into resignation. Thoughts? — Rogue WH Snr Advisor (@RogueSNRadvisor) September 25, 2018

Chris Rock couldn’t have made that United Nations crowd laugh any louder than they did at Trump lying about his accomplishments. That’s what happens when he tries his MAGA rally nonsense on people who aren’t completely brainwashed. — Adam Best (@adamcbest) September 25, 2018
