Trump on Monday railed against Canada by threatening it over a bridge and then warning that China wanted to “terminate” hockey in Canada and “permanently eliminate the Stanley Cup.”

The president’s bizarre comments left Kimmel baffled.

“Did he get hit in the brain with a hockey puck or something? I mean, seriously. China is gonna ban hockey in Canada?” he said. “We got a code orange demental emergency going on here right now. He’s gone. He’s totally gone.”

Trump’s threats left Kimmel with so many questions.

“How would China ban hockey in Canada? Would they take all the hockey sticks, make ’em into chopsticks?” he wondered. “And why would they ban hockey in Canada? What purpose would that serve? I think you might need to give this one a little bit more thought.”

He said maybe Trump has been watching “Heated Rivalry,” the HBO Max romance about gay hockey players, “and isn’t sure where to put those feelings he hasn’t experienced before.”

The bridge at the heart of Trump’s latest complaint is set to connect Windsor, Ontario, and Detroit, Michigan. It was financed by Canada and is called the Gordie Howe International Bridge, named for the Canadian hockey player who spent most of his career with the Detroit Red Wings.

“Come on, Canada, you know how this works,” Kimmel said. “Pull out the Sharpie, cross out the ‘Gordie Howe,’ write in the ‘Donald Trump,’ and everybody can relax, all right?”
