I did all sorts of stupid crap, mostly when I was between 10 and 15, some of it I can't remember. I think at one stage my friend and I took this annoying kid's shoes off and stole his socks, then I climbed a huge tree and tried em to the top.
I remember pranking this asshole, it was when everybody at school was buying Sprite Zero and some other blue soft drink so we took an empty bottle and went to the upstairs toilets. I took a monster piss in it and then we dropped in blue ink and shook it up before throwing it out of the window onto the bench he always sits at. It took him a while to realize he was covered in urine, not soft drink.
Not sure what else I got, I was suspended heaps but I think that was just from fights. I would often do this joke, I'd tuck my knees and stretch my shirt over them then pull my arms into the sleeves so only my wrist and hands were out so I'd look like a midget. I was trying all sorts of things but when I was rolling down this wheelchair ramp on my side really fast, I smashed my head on one of the rail's poles, that was funny as hell.
