Boat launch Story

So this weekend is Sea Fair in Seattle. If your are into making some popcorn and watching idiots unload boats, then this is the day to do it. I am getting ready to go to chelan with my family and me and my cousin had to ride the Sea Doo's over to the launch. I was observing some people putting their boat in and I could tell this was coming. They started backing down the ramp and got the boat trailer about halfway in the water and to them that was as far as they needed to go. The dad got back in the truck as the mom pulled the oposite direction with the bowline (the boat wasn't anywhere close to floating) and she puts all of her weight into it and the dad punches it. I was watching all of this in slow motion laughing before it happened. The boat bounced and the trailer flew out from beneath it and the mom fell on her butt. Because the trailer was only half way in the water, the boat went KABOOOM! on the concrete of the launch making a smashing/cracking noise as it settled. The dad got out and all three grinded it on the concrete into the water as it happened everytime. Got any other funny stories??
