A programmer is told by his wife, "go to the store and get a loaf of bread. If they have eggs, get a dozen. The programmer returns with 12 loaves of bread. His wife screams, "Why di you get 12 loaves of bread?!" He replies "they didn't have eggs.
I don’t get it, they were only supposed to get a dozen loaves of bread if they had eggs, since they didn’t have eggs, it should only be one loaf of bread.
I think the reply should be "they had eggs".
