There have been a number of oddities during my golfing career. The one that stands out the most where I was hitting a shot happened last year. I pushed my 2nd shot on a par 5 to the right on the opposite hole. About 50 yards in front of me, there was a guy mowing the grass in line with the hole. I tell him to move since he's in my way and only moves about five feet to the right. I hesitate, knowing it's not nearly enough, but he just stands there looking at me holding his ground. I end up hitting a screamer no more than 10 feet off the ground, forcing him to hit the deck.
As for playing partners, my dad once hit himself. It was a par 5 that doglegged left. His first pushed right along a treeline, but he still had a favorable angle coming back. Unfortunately for him, he pushed his shot right, struck a tree, and nailed himself right in the Twins bullpen. Luckily, he was okay (and I, already born), but he definitely took a shot.
Lastly, I've come to believe in reverse-karma. Same course, following hole as the first story. We were waiting for a par 3 to clear and my friend was getting impatient. He was messing around with his 3-wood that he won in a closest-to-the-pin contest, but never had the chance to use. 90 degrees to his left, he saw an opening between the tips of the trees. He teed up a old ball, and pounded it. A few seconds later, we heard what sounded like a car crash. The main road went perpendicular to his ill-advised shot and struck a car. Said car actually went in reverse maybe a fifth of a mile to see what happened as my friend tried to look as innocent as possible (the guy drove away a few seconds later). As I left the course at the end of the day, a bladed shot went through the previous hole and hit the hood of my Civic. No significant damage, but the golf gods really should have punished the guy who hit the shot.
