Willem discovered last night that if one has a crown and one flosses a tad too enthusiastically, one can pop that crown right out.

He also discovered that if he walks over to me and says, "My crown just fell out," and I don't quite understand what he said, and he holds out his hand and shows me a tooth sitting in it, I will have a moderate freakout and momentarily believe that his entire head has just broken into small pieces.
