Get the Reverse Upper Deckermug. Same as the standard upper decker except you eat a 20-pack of White Castles first and then take the massive dump in the tank. when the next poor slob flushes, the smell from the dirty water will cause an uncontrollable craving for White Castles.
When my ass was about to explode from that 20-pack of castles I ate, I gave marco's toilet a jersey upper decker.
