Before you read this, keep in my that my elementary school was full of 'special' kids and... well, handicaps.
In fourth grade, my friends and I were playing tag when we had a good 30 minutes left before school started. I was running around trying to find a place to hide it out and watch. I ran under the playset. (This playset included a somewhat see-through bridge that was about 7 feet off the ground and about 6 feet long.) Anyway, I was running under the bridge to suddenly stop at a strange sight... There was a stream of dark yellow liquid flying through the air and into a puddle in the wood-chips that coated the play area. Naturally, after seeing this I quickly recoiled and backed away. Looking to the right, I see one of the downey children with his pants off (scattered around the play area) peeing in plain sight...
I quickly looked away and looked back a second later to see that the kid had stopped peeing and a teacher was picking him up and running into a room... pants still down. I looked around and saw that there was a circle of other classmates around the crime scene. Some were laughing, some were staring at the puddle of urine that was slowly soaking into the ground...
You get the idea.
