First guy : "Hey, sir ! I'm looking for my girl friend. Can't find her anywhere !"
Second guy : "What a coincidence. I'm looking for mine too. Can't find mine either !"
First guy : "Maybe we can help each other find both of them. How does your girl friend look like ?"
Second guy : "Slim, blonde, long legs, short leather skirt, and she has a firm pair of breasts. And how does yours look like ?"
First guy : "Doesn't matter. Let's go and find yours !"
