A programmer’s wife says:
“Honey, can you go to the store and buy a loaf of bread? If they have eggs, buy a dozen.”
The programmer nods, grabs his wallet, and leaves.
Twenty minutes later, he returns struggling with a huge bag full of bread.
Wife (shocked): “What on earth happened? Why did you buy twelve loaves of bread?!”
Programmer (completely serious): “Because they had eggs.”
