A software engineer is about to head home and texts her husband: "Want anything from the store?"
The husband texts back: "Get a quart of milk and if they have eggs, get twelve."
The software engineer gets home and puts a bag on the kitchen counter.
The husband looks in and says, "Wait, but... why did you get 12 quarts of milk?"
She looks at him like he's stupid: "They had eggs!"
