i know someone who crap in their own hand for ten dollars.
when i was about 8, i had the door open while pooping. either my brother or sister played some prank on me, so i chased after them, and laid a nice little turd on the floor in the process.
need to wash hands, even if its just a bit of water, no soap. sometimes you don't taint-press long enough, and it generally is a sweaty area.
saw on the discovery channel that every time you flush, a turd cloud rises up, putting microscopic bits of turd on everything in the surrounding area. so i flush with the seat down.
