I was helping friends load an engine into the back of a pickup once, and the hoist got stuck so we backed the truck under the motor. I was holding the thing steady while he backed the truck up, and he stopped right on my foot! Not once, but twice! He didn't know what all the yelling was about the first time, and I should've learned before it happened again. I gots big feet, and luckily nothing broke(in my foot!)

I also remember as kids, we used to build firecracker bombs by taping as many as we could together and twisting the wicks, then lighting them and running. We also used to fill soda cans with firecrackers and match heads, and rig a wick to it. Those suckers were pretty neat, minus the aluminum shrapnel.
Didja notice how a lot of these stupid things have to do with fire...
