Naked Sunshine Time

We have this thing in our family that Bill started called "naked sunshine time" where all the boys go outside on the trampoline in just their undies and get a little sun. We only go out during "good sunshine" hours, which are apparetnly before noon and after four. I normally do not participate in the "naked" part, but when I lose my weight I'll probably throw on a bathing suit and join them, who doesn't need a little color?
