There are many things we'd advise against when hanging out with Mike Tyson; poking fun at his face tattoo, challenging him to a fight, insulting his role in The Hangover. Now we can add "sleeping" to the ever-growing list.
UFC president Dana White was none-too-pleased with having the word "DiCK" written on his forehead with a Sharpie. Perhaps it's because it takes a while for a permanent marker to disappear, maybe it's because he didn't approve of Tyson's mixture of lower and upper case -- but either way the former heavyweight champ made his feelings known.
This was a pretty eventful flight for the two pillars of professional fighting. Before the dickhead incident Tyson kicked White out of his plane seat because he wanted to sit there, and while the whole back-and-forth was probably staged for laughs we're still enjoying it.
