What’s the dumbest thing you’ve seen or done on a golf course?

For me it was the time I tapped this guys tail to get him away from my ball at Streamsong.

As a kid, my dad put me into some lessons with friends (unfortunately forgot everything from those when I picked up the game again a few years ago). The group from my class who was ahead of us was goofing off on the green instead of moving to the next whole, so my friends and I collectively shouted "move." They proceeded to moon us. I had my ball teed up already, so I angrily hit at them and was about a meter away from hitting one of them in the head. Looking back on it, I'm grateful nobody got hurt and realize just how bad things could have been if I'd hit the idiot in the head.
