A huge guy marries a tiny girl, and at the wedding, one of his 
friends says to him, "How the hell do the two of you have sex?"

The big guy says, "I just sit there, naked, on a chair, she sits 
on top, and I bob her up and down."

His friend says, "You know, that don't sound too bad."

The big guy says, "Well, it's kind of like jerking off, only I got 
somebody to talk to."
