When I was younger my mother used to look after other peoples kids while they were at work. I must have been about nine at the time and one of the kids that came round to my house a lot was a right little bastard (he was about 6 years old). One day when he was actually behaving I got an empty bowl from the kitchen and filled it up with rabbit shit (we had pet rabbits), I took it over to the kid and told him it was cholocate cereal and got him to eat it. He ended up being ill for a few days after but I thought that it was hilarious.
