Good Year vs. Great Year

Listen up, buttercup! You, who probably thinks a 'Good Year' is just when you don't spill your cereal, need to get with the program! This joke is playing on two things, ya dingbat. First, 'Goodyear' is a famous tire brand. See? Like the rubber thing on a car! Second, '365 used condoms' implies someone was super busy, like, every day for a whole year. So, 'one's a Good Year' (the tire) and 'the other's a great year' (because of all the fun, if you catch my drift, slowpoke). Get it now? Probably not, you big dummy.
