Warning: Rant follows.
The little scrub brush is provided next to the toilet for a reason. If you take a splatter-filled power-dump in my toilet, for the love of all that’s holy, please take a moment to scrape your leftover high-velocity corn scraps into the water.
You see, corn makes a natural sort of glue, and if your partially-digested diarrheal remains stay on the porcelain for more than a few minutes, I must scrub vigorously to remove them. I have better things to do than energetically scratch the overindulgent streaks from your gas-assisted rectal explosives from my bathroom.
Perhaps a small sign like “Please use the scrub brush before you leave” might do the trick. What I really want to say is “Nobody wants to see what’s left of your butt-warhead, Nimrod, so please clean up your skid marks.”
But that wouldn’t be a polite reminder, would it?
