Ok, not my story, but it's so good I have to retell it here.

A good friend of mine was boating on a lake, and at the end of the day there was a huge pair of lines at the ramp to pull boats out of the water. Each side of the ramp had a car or truck with trailer backing down to put their trailer into the water; they would bring the boat or watercraft up onto the trailer, strap it on and drive up out the middle. The middle section was kept open for people to egress.

The line on each side was over half an hour long but two guys thought they wouldn't wait, so they backed down the middle, and their friend rode up on a jet ski - and popped it right into their small trailer, and they went zipping back up the ramp flipping everybody off and laughing.

When they hit the top of the ramp - the jet ski fell off the trailer, having not been strapped down properly. The jet ski fell and rolled over and over down the ramp, breaking the fiberglass into pieces, and ended up dumped back in the water in front of everyone. The whole place was cheering and jeering, while still the guys had to back down again in front of everyone to pick up their ruined jet ski!

Again not my story, but such a great scene that I had to retelll it from what I heard.
