We were casting a bay one evening when 2 clowns on a jetski decided to mess around with us. They came in close and started doing donuts around us for about 5 minutes then took off. They only got 100 yards and tried to make another sharp turn but instead rolled the machine over. We could hear one of them screaming in pain in the water so we motored over and asked if he was hurt and he said yes, it's my back. I said "ahhh, that's a shame" and continued on our way.
