My freshman year in HS we were having an alcohol party at a friend's house, as I was climbing up the stairs to the second floor another one of my other buddies (who happens to be black) leaped out at me wearing nothing but his skivvy drawers and a tie (catholic school remember) wrapped around his forehead.
He loudly proclaimed "I'm Rambro!".
To this day I don't regret pushing him down the stairs (he wasn't injured).
