the best poo-poo experiment i ever had was after thanksgiving dinner. i ate so much i thought my panties would be ruined. i spent a long time on the toilet, plus i took a few special magazines to read. well, not read, but you know, to look at all the hairy dudes butts and balls. i couldn't bring myself to flush the toilet, the pile was so big i wanted my family to see it. boy, did they ever see it. my dad spanked my naked butt so hard, it stayed red. never went back to being white.
and that was my best ever poo-poo experiment.
