While banging a broad from behind, make sure she is facing the head board or some other hard suface and wrap your hand around her hair while humming or whistling the "Pop goes the Weasle" tune. When you get to the big "Pop" toward the end, slam her face as hard as you can
Hey I gave her the jack in the box last night. Check out her face!!!
