Mike Tyson, of Mike Tyson's Punch-Out, was one of the most fearsome Nintendo bosses of any '80s kid's childhood. He hit extremely hard, and it was hard to hit him back. So it's understandable that the real Mike Tyson might be a little nervous to face himself in his 8-bit prime.
"I would get killed, man!" he protests to Tyson-on-Tyson fight promoter Jimmy Fallon. He's only ever met one person, a 10-year-old kid, who claimed to have beaten the NES version of him. But what the hell, he'll give it a try.
