Ok, I was about 7 or 8 when this happened....
We used to have a big picnic table in our backyard, with a metal frame, It probably weighed 300lbs. Well for some reason my parents leaned it up on the side of the fence, (witht the bottom facing away from the fence) to mow the lawn or something...
So I decided to make a ride out of the table, by tying a chain to it and hooking it to the fence. Then I climbed on the bottom of the table, and held on to the metal frame. I leaned forward, and the table fell, and the chain stopped it from falling all the way to the ground....
I did this about 3 times, and had my sister do it a couple of times. Then, I tried it once more, but this time the fence snapped in half and the picnic table fell on me.
I wasnt hurt though, because I was in-between the metal frame, underneath. But it sure did scare the shit out of me.
