I was at the game where Pete Rose broke Ty Cobb's record for base hits. It sounds like it's a good thing Ty wasn't there.
Sitting in the stadium a few rows behind the team bench, a sports fan insulted a hot-tempered player with a constant stream of taunts and slurs.
The player responded by climbing into the stands and beating the fan so savagely the player was suspended from the league indefinitely.
The year was 1912. The baseball player was Ty Cobb, who sought revenge despite the fact his heckler was missing one hand and part of his other one. When somebody pointed out the man's handicap, Cobb reportedly said, "I don't care if he has no feet."

I didn't realize that Ty Cobb was such a jerk until I listened to Wait Wait on NPR last week. They alluded to this story, and I had to go dig it up.
