What's the dumbest reason for two grown men to get into a fight? Whatever your answer is, you're wrong. Two, um, "gentlemen" got in a heated "disagreement" when a dirt bike rider crossed paths with a man on an ATV. The dirt biker was speeding, the ATV driver started shouting, and frankly, their arguing made less and less sense as it went on. When their altercation was over, neither man really walked away a winner.
