Two cowboys are out on the range talking about their favorite sex positions.
One says "I think I enjoy the rodeo position the best."
"I don't think I have ever heard of that one," says the other cowboy. "What is i t?"
"Well, it's where you get your girlfriend on all fours, mount her from behind, and reach around and cup her breasts in your hands. Then you whisper in her ear, 'Boy, these feel just like your sister's,' and then try to hold on for 8 seconds."
