Two guys are moving about in a supermarket when their carts collide. 

One says to the other, "I'm sorry - I was looking for my wife."

"What a coincidence, so am I, and I'm getting a little desperate."

"Well, maybe I can help you. What does your wife look like?"

"She's tall, with long hair, long legs, firm boobs and a tight ass. 

What's your wife look like?"

"Never mind, let's look for yours!"
