The Resprinklification of Cupcakes

I came up with the following idea the other day, and it seems to work well. You know how some people prefer the tops of muffins? Well, Meir prefers the tops of cupcakes, and on the occasion that I get him one, he only eats the top. This is a waste of a cupcake. So I got some rainbow sprinkles from the local grocery, and sprinkled them on top of the now-barren cupcake. 40 seconds in the microwave to get them to melt on the top, a few minutes in the refrigerator to cool, and they are good as new, and he'll eat more. (I don't first put on a layer of frosting, as they do when they first bake them.)
