Boys will be boys

Where is it written that if it's dirty, gross or will freak someone out a boy must try it? Youngest was caught this morning scrubbing the floor with *MY* electric toothbrush. Now I appreciate his diligence and willingness to ease the burden of the cleaning for his Mom but really? My toothbrush? I do carry some of the blame what with actually using old toothburshes to clean nooks and crannies around the house. But it's not like I left it out somewhere and it just called his name. He had to go get it out of my drawer in my bathroom in my bedroom. Now that's commitment. *Sigh* At least he was being productive.
