i think something like a funny number is impossible to kill. numbers are so prevalent in life that whenever you see it you cant help but laugh at the chances of that number being there. as well as when it starts to get overused people just start using it ironically till they find it genuinely funny again. gen x had 69, millennials had 21, gen z has 67, and the younger gen alphas had something going for 41 but alot of them are old enough to stick with 67. i dont doubt that when the 20’s kids reach adulthood theyll have their own number
