''Iron'' Mike Tyson beats the crap out of a passenger on a Wednesday night flight

The video below shows Tyson delivering multiple punches to the face and head of the passenger behind him. Apparently the guy had it coming though.

Per sources close to the matter, as TMZ reports, the man was drunk and belligerent, relentlessly harassing Tyson despite the champ's pleas for him to leave him alone. You know what they say about poking the bear..

Apparently, Tyson really did not want to engage the intoxicated male, but he drew the line when the man threw a water bottle at him. I mean, call me crazy, but I don't think Tyson is the guy you really want to be provoking. He got what was coming to him, IMO.
