Back in college I caddied at a mid-level club in the Chicagoland area. The 3rd hole was a very narrow par 4 that was heavily wooded on either side of the landing area. It was common for many golf balls to get hammered into the woods and never be seen again. When groups got on the tee they usually sent a caddie ahead to watch tee shots from the landing area. After some time, the club outlawed this practice becasue it was deemed too dangerous, since a couple of caddies had close calls with getting beaned, and the club was worried about getting sued.
Well, one day the group I was in had 4 members and 4 caddies. One of the members had his son on the bag. The member told his son to go down to the landing area and spot balls. The son, rightly so, said, "Dad, the club doesn't want us down there anymore."
Of course, the dad pulled out the "I'm your father and I say go down there" card, so off the young lad went to sit along the treeline on the right side of the hole. Three balls ended up in the fairway. The fourth, the dad member's ball, went screaming along the treeline on the right.
The hole sloped downward a bit so the landing area could not be seen from the tee. The group, and now 3 caddies, walked down to the landing area. When we got down there, sure enough, there lay the son caddie knocked out cold by his father's wayward drive, massive welt on his forehead, bag by his side, golf ball not 20 feet away.
