Sometimes stunts are funny.  Sometimes they're gross.  Sometimes they're pointless.  The guy in this video below seems to be one of the rare few to hit the "Funny/Gross/Pointless Trifecta".  As the video starts, he's trash-talking to a cactus and pretending to box it.  Then, it cuts to him standing on the hood of a car.  That's when the gross begins.

Based on his reaction, things went a lot worse than he thought.  What exactly was he expecting to happen?
