A cardboard box, markers, and two kido's

Russ brought a box home from work and he and the kids went to town building a hut. Anybody else have fond memories of playing in refridgerator boxes as a child? The kids have had hours of fun with this and colored it completely. Why do we spend money on toys, when a free box gets used just as much? If you are wondering the drawing on the front...Joshua is a fisherman and has caught Lexie (the bunny) on his fishing pole.(don't ask...I don't have an answer..)
