Dax Shepard reveals Mike Tyson once threatened him at NBA All-Star Game

Mike Tyson doesn't take too kindly to people grabbing his shoulder.

During an appearance on "Watch What Happens Live with Andy Cohen," Dax Shepard recalled the time he was threatened by Tyson at an NBA All-Star Game. The two had met a week prior, but Tyson apparently didn't remember, because when Shepard placed his hand on Tyson's shoulder, he lashed out.

"If you don't take your hand off my shoulder, I'm gonna break your f---ing head open," Shepard said Tyson told him.

"I thought he was joking," Shepard said. "And then he escalated it, and then I took my hand off his shoulder."

Good call.
