A husband and wife were grocery shopping. He picks up a case of beer and puts in the cart. "what are you doing?" asks the wife. "They're on sale, only $10 for 24 cans" he replies. "put them back, we can't afford them" demands the wife. They continue shopping. Later on, she puts a $20 jar of face cream in the basket. "What are you doing?" asks the husband. "It's my face cream. It makes me look beautiful" replies the wife. He said "so does 24 cans of beer and it's half the price!"
