At my old school we had an annual fete, and every year there would be a raffle. The prizes would be boxes made up of items that parents and others had donated, and there were different categories, such as the 'Chocolate' box, the 'Bathroom' box and, by far the best, the 'Surprise' box, where the mystery contents were wrapped in fancy paper!
One day, walking across the playground, my friend and I saw a nice ripe piece of dogshit; so we got a cereal box, stole some tape and some pink poster paper, and wrapped our piece of shit up, slipping it in to the 'Surprise' box before lunch.
Sadly, we never found out who won the 'Surprise' box, but we hope whoever it was one day visits this wonderful website and realizes it was me that gave them a big shit in a Coco Pops box.
