You can learn a lot about a YouTube video by the description the author gives it. So when you see something like this: "My brother decided it would be a good idea to roll a bowling bar from a fast moving car onto a launch ramp…" you know you're about to see retards at the top of their game.
Incidentally, I'm 95% certain this is filmed somewhere in the Mojave Desert. Having lived there for over three years, I'm actually kind of surprised that I never tried this. Then again, I didn't have a bowling ball. Or a ramp. All I had to keep me company was scotch. That's how we got to be such good friends.
