There’s an old programming joke that still makes me laugh:
A wife asks her husband, a computer programmer; “Could you please go to the store for me and buy one carton of milk, and if they have eggs, get 6!”
A short time later the husband comes back with 6 cartons of milk.
“Why on earth did you buy 6 cartons of milk?” The wife asks him.
He replies, “Because they had eggs.”
