I have some of my own.

Today at the park, DS2.8 vehemently refused to play on the equipment, and instead initiated a game of "mathematical hotdog vendor". He created little arithmetic problems using hotdogs he made out of sand. The highlight for me was, "If I cook 6 hot dogs and Daddy eats 4 (!!), how many will be left?" He proceeded to impersonate DH bolting the hotdogs. In all fairness, DH is no glutton

We also built a pyramid in the sand, and DS told me he was carving out the Nile next to it.
What is to give light must endure burning.
