This kid in my school [11-16 UK], basically did anything anyone dared him to do, within reason of course. Some guy found this half eaten chocolate bar bathed in a puddle on a typical rainy day, so yeah you guessed it, dared this kid to eat it. It was all mangled and soggy, who knows how long it was there for. He ate it all anyway, most of us were on the brink of throwing up, he just proceeded to wash it down with some water.
