Here's how not to tear down an above-ground pool. There's a video online of a group of friends who built a ramp and tried to jump their JEEP into one, then drive out the other side of it.
And they actually managed to pull the first part off. But then the Jeep landed in the pool and stopped dead. So they had to grab a power saw and cut through one side of the pool. According to guy who posted the video, the Jeep still runs.
