Bruce Jenner's beef with Jimmy Fallon started during last year's summer Olympics, when the comedian cracked jokes about the reality TV dad's plastic surgery. Fallon has since said that the former Olympian told him: "Stop saying sh** about my face."
The 63-year-old brought up the subject during his "Late Night" appearance on Tuesday. But his attempts at jovial ribbing came off forced and partly serious.
He said Fallon acted like a "wimp" during their 2012 confrontation, talked up his "good friend Kanye," and mocked Fallon's appearance.
“You can make all the jokes you want, but I guarantee you, Mr. Fallon, that my ass in a good pair of running shorts, looks a hell of a lot better than your ass," Jenner said.
