A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it. It was supposedly invented by Pythagoras of Samos (yes, that one). It allows the user to fill the cup with wine up to a certain level. If the user fills only to that level, the imbiber may enjoy a drink in peace. If, however, the user gets greedy, the cup dumps all the wine into the unfortunate victim’s lap.
Green Day lead singer Billie Joe Armstrong wrote this about his father, who died of cancer on September 1st, 1982. At his father’s funeral, Billie cried, ran home and locked himself in his room. When his mother got home and knocked on the door to Billie’s room, Billie simply said, “Wake me up when September ends.”
So I’d be angry too if people kept this shit up every single year.
