A wife asked her husband to go shopping for their weekly groceries. “Can you go and buy one carton of milk and if they have tomatoes, get six,” she told him.
The husband agreed and headed off to the shops. An hour later he walked back into the house with six cartons of milk.
“Why on earth did you buy six bloody cartons of milk?!” the wife asked her husband in shock.
The husband shrugged and replied, “Well, they had tomatoes.”
