A husband and wife are at the grocery store. The husband picks up a case of beer and puts it in the cart. The wife asks, "What are you doing?" He says, "The beer is on sale, 24 cans for $10." She says, "We can't afford that so put it back!" A few isles later the wife puts a $20 tube of face cream in the cart. The husband asks, "What is that for?" The wife says, "It makes my face pretty." The husband replies, "So does 24 cans of beer and it's half the price!"
