"Our revenues cross borders. So do our sports leagues. Baseball, basketball, hockey," Biden said. "I have to say, I like your teams, except the [Toronto Maple] Leafs."

His reasoning? He's still bummed about a Philadelphia Flyers' loss to Toronto earlier this year.

"They beat the Flyers back in January, that's why. And if I didn't say that — I married a Philly girl — if I didn't say that, I'd be sleeping alone. Fellas, I like you, but not that much," Biden quipped.

Back on Jan. 8, the Flyers hosted the Leafs but lost, 6-2.
