Trump, while signing a bill to bring back the Presidential Fitness Test, ranted about the election, Iran, the planned UFC fight on the White House lawn, how much he deserved a Nobel Peace Prize and more.

Kimmel played a clip in which Trump also complained about “transgender mutilization.” Realizing he was surrounded by children, Trump added, “Don’t listen to this, kids” and then kept going.

“This man is insane, OK?” he said after playing the clip. “He made up a word, ‘mutilization,’ and he’s telling children about it. Next thing you know, he’ll be telling them his favorite story, the tale of the lady weightlifter.”

Sure enough, in the next clip, the president was repeating a story he often told on the campaign trail about a transgender weightlifter.

“Very, very normal,” Kimmel deadpanned. “Just a totally lucid, very rational, clear-minded, level-headed person sharing his thoughts on gender reassignment with a group of young kids. That’s our guy.”
