Hehe...one that haunts me to this day.
At elementary school, there was a wooden plank bridge. It had a rope go through planks, and when t=you steped on them they would move back and forther, depending on where you step on them.
My grade 7 class and I were playing ball tag on this park. As I ran across the bridge I fell through one fo those planks, because the rope snapped.
Understand this: I weighed around 120-130 at that time, and that rope was metalic, and was about 2 CM thick. there were two of them.
That's not the end though, so O.K. I fall through. one leg is in the gap, the other is not. My two legs are forming a rather painful 130 degree angle. My crotch is under severe pressure (

) from being streched and held against the wood.
Done? Nahh not yet.
So there I am getting a free sex change and becoming more flexible at the same time, when one of my arch-enemies decides it'd be a great time to cause some pain! (yay!) So there he goes, cranking my leg that's lodged between the wood, twisting and turning it (and through all this no friends of mine help, they said they hurt more than I did they laughed so hard, though I'd have to doubt it).
After 10 minutes of screeching screaming bloody murder and loads of laughter, I was helped out of the gap and needed the help of friends to get to my bus.
All true, no exagurations.
