As a whole, baseball players are an eccentric group. They walk in circles around the pitching mound talking to themselves. They take bathroom breaks in left field walls. They shove cameras and snuff reporters.
Yet over the course of baseball history, there have been several individuals who have made themselves stand out from the crowd. Some of them have had illustrious careers, yet ruined their reputations by stupidity, plain and simple. Others were journeymen who made a name for themselves by one or several acts of idiocy.
This is not a ranking of the dumbest players. This is simply a list of the players and their respective transgressions. Prepare to feel better about yourself—it's not hard to be smarter than these guys.
