I got to see this in real life...or is that real-time?
The parents have a place in Fremont WI. SirP, not too far from you now.
There's a boat landing that splits their property right down the middle. House on one side, boathouse on the other. I was walking over to the boathouse. Guy in a Suburban was gonna be pulling his boat out. He backed too far into the water, and wasn't making any headway in getting out. The part of the landing that's underwater is generally moss-covered, and all he was doing was spinning his wheels.
This ass hat decides he's not gonna be able to get out the regular way, and figures out what he thinks is a crack scheme. He has the wife get in the truck, and he jumps in the boat. He starts it up, and runs it up as far as it'll go. At this point, I'm thinking "this is gonna be a learning experience one way or the other, I may as well sit down and watch this"
He tells the wife he's gonna gun the boat to kinda "push" the trailer up out of the water, or at the very least, take enough pressure off it to allow the Suburban to get out. I wasn't very old, but I was smart enough to see (and say to myself) the ass hat's boat was FLOATING in the water, and was only pushing the smallest slice of the trailer. He says "Wait'll I say, and then gun it and don't let off the gas until it's headed up the ramp"
He has the boat moter in neutral, starts to rev it up, and yells "OK!". She starts to slide, he drops the motor into gear, hits the smallest little piece of the trailer and shoots over it. The point of the boat smashes his back window, shoves the Suburban, but at that moment, she must have been sliding one way and tried to compensate, and the force starts her sliding even more, and into the water she goes, right up to the windows!
He calls his buddy to come drag him out. They DON'T have a winch, just 2 chains. While his buddy is trying to drag out his buried Suburban, he ends up smoking one of his wheels and ends up with a flat!
The moral of the story?
Boats are bad, mmkay?

p.s. It probably didn't help their mood at all that some smart-ass young punk couldn't help but almost laugh himself off his dock and almost piss his pants. I didn't ask them, but I'm pretty sure knowing what I know now, I'd probably kill that little kid for laughing at the situation
