What better lead can we have going into this list then the Richie Incognito/Jonathan Martin situation? The "hazing" incident is dominating the NFL media cycle these days, but, it isn't nearly the first such transgression behind the sporting world's closed doors. After all, the locker room is a sacred place where an athlete is allowed to drop his guard, share his inner most feelings, and smile like a madman while getting his bare ass slapped by teammates (we see you, Anthony). Unfortunately, the room is often off-limits. It really makes you wonder about the bullying and blatant homoeroticism that's been covered up since the days of Babe Ruth. Here is a brief history of insane locker room stories. You could probably make dozens of these lists with all of the tales that never got out; but here's a fraction of that which could not be covered up.
Note: We realize that the Penn State football locker rooms were the setting for truly insane behavior. But, it was a style decision to avoid that scandal for this list.
