Mike Tyson looks like a happy camper on the heels of punching the crap out of an annoying passenger on an airplane ... and he's more than happy to take selfies with adoring fans.
Iron Mike rolled up to his Miami hotel Thursday evening in Miami -- he's in town for a cannabis conference, and he took time to greet folks outside the lobby. He was trying to get to Miami on Wednesday when he boarded that JetBlue flight in San Fran.
This is the first public sighting of MT since we first posted the video of him raining down blows on the man who was seated behind him on the plane.
