Mike Tyson lost his cool on a plane on Wednesday night and repeatedly punched a man in the face after the guy had apparently annoyed him!
A witness on the plane says as the guy and his friend were boarding Mike Tyson's flight and he was initially cool with them and the other passengers.
The witness told TMZ that Mike took a selfie with him and then was patient with his overly excited man, who kept trying to talk to him (his seat was right behind Mike's).
Eventually, though, we're told Tyson had enough of the guy behind him talking in his ear ... and told him to chill. When the guy didn't, that's when the witness says Tyson started to throw several punches at the man's face.
The guy got pretty bloodied up and word is he went to the police after the incident. No word on an arrest on Mike Tyson yet.
