Insane, something nutty and then something funny!
9. The Self Destructor
How it works: When someone breaks your windows and steals your car and they throw it into first, the wheel tugs on the chain which in turn tugs on the rear bumper. When the bumper reaches its breaking point, the wheel sucks it underneath the tire and shatters it. Free from the bumper, the chain then rotates with the accelerated wheel, thrashing the side of your car and ripping off all the paint.
If you manage to recover your car, it will look like fucksake. So just hope that the thieves cut your chain to prevent causing you more trouble than stealing your car already does.
And then there is this!
4. The Petty Protector
High ticket item. Most frequently used as a prank aimed at a wasted friend. Try locking a passed-out, bracelet-wearing friend to the refrigerator for best results.
