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, Yeah well, it's kind of like jerking off, only I got somebody to talk to.
