The Pythagorean cup was the original Whoopie cushion. It disguises itself as a normal drinking cup but features a contraption that’ll completely spill your beverage if you pour above a certain level. It is commonly dubbed the “Greedy Cup” because it prevents frisky individuals from taking more than their share, embarrassing them in the process. It is often credited to the brilliant mind of “Pythagoras of Samos”. Though you can’t travel back in time to cop one from Pythagoras himself, there are some pretty nifty replicas on Amazon.
“Brothers, turn your gaze upon Publius! He has poured himself a drop too much of wine into the greedy cup! What a fool.”
