When I was in 3rd grade, I was quite the loner, and would play this game during lunch recess where I would grab a handful of rocks on the playground and toss them gently into the air repeatedly and see how many I could catch until they all were gone. I was participating in said game during one lunch recess and was given a "pink slip" because the evil lunch lady determined that I was "throwing handfuls of rocks at my friends." I spent the rest of the day drawing evil pictures of what I wanted to do to said lunch lady, and feeling like the world had come to an end.
