Then dentist gave him the cutest little wooden box shaped like a tooth with a lid that swivelled out of the way to put the teeth in. TF took the teeth and folded the bill up REALLY small to fit in the space (about the size of a stack of 5 nickels).
Needless to say, he was thrilled with the money! That puts him closer to being able to buy one of the Lego Spybotics so he can do some more programming with his Lego Mindstorms set.
