Target launch

Pretty much all you do is stick someone on the seat, drive a car off the ramp and try to hit the target. This will launch whoever is on it onto a trampoline and then they will bounce into a pool filled with crap.

variations include: Taking out or adding a trampoline, making the pool full of piss, firing weapons(of your choice) at him, or adding a light electrocuting shock(usually by a tazer) to the piss.
