Practice round for our high school regional tournament, sometime back in the mid-1990's. On the 18th hole, one of my teammates pushes his tee shot wide right, nearly on to the adjacent 16th hole. As he approaches his ball, a member of one of our rival teams is coming up 16 and makes the comment, "Nice shot, no chance you'll be holding a trophy this tournament". Teammate immediately drops his Ping hoofer, raises his fists and goes at the guy saying, "no problem, neither will you after I break your jaw" Cooler heads prevailed and it didn't escalate beyond a few more verbal exchanges.
Over pizza that night, we asked our teammate why he didn't pull out a sand wedge to go at the guy. His response? "A proper golfer never uses his clubs in a fight". Words to live by, I guess.
