Here's the scene:
Computer room is next to the boys room, you can hear sooo much. DS 7 1/2 and DS5 bought a $1 basketball hoop that attaches to the top of the door. They have made a ball from foil.
I am surfing the net and I hear much chatter. Then I hear some noise and movement. I realize they have pushed a rubber maid box out of their closet and are now jumping off of it and "slam dunking" the foil ball in the net. They are hooping and hollaring. "slam dunk" "high five" I mean the testosterone is thick in there! Harmless, well as harmless as two boys in a small area jumping off a rubber maid container towards a closet door can be! 
I hear a crash..........DS 7 1/2 to DS5 in a VERY firm and parental voice "See what can HAPPEN! That is not what it is made for!!!!!!" We breed geniuses here, folks, geniuses!!!
And the rubber made container and the wall will NEVER be the same!
