sure, 420 and 69 are good and have been around forever, but i'm afraid they are on the verge of becoming stale
therefore, i believe the best course of action is to begin incorporating new numbers with humorous implications into our ever-growing slang
i personally suggest 28980 and 6.08695652174, which are the product and quotient, respectively, of 420 and 69
a rather refreshing spin on two classics if you ask me
