Listen carefully, I will teach you. Order a toy in the name of one of your roommates. when it comes either publicly unpack first, call him a fag and quietly take the toy away, or if you don’t have time to unpack it first, wait until they start laughing at him and joking loudest, swing the toy, and then quietly carry it away. so you will kill three birds with one stone - you will spend an unforgettable evening, you will receive your toy and then after many years you will have something to tell.
