The parents of a friend of mine in high school moved into a new house, with a totally unfinished basement. It was huge. And it was filled with moving boxes, etc.

We ended up arranging the boxes into "forts" and barricades, and had BB Gun fights. We were smart enough to wear safety goggles we'd ripped off from chemistry class, but we still ended up with many subcutaneous BB's and their resulting infections for about a month... until his parents unpacked all their stuff.
