There was a little girl and a little boy walking down the street when suddenly they see two cows fucking. The girl asks, "What are they doing?", and the boy replies, "Oh they are jump roping." So, they continue to walk and see two dogs fucking. The girl confused again asks, " What are they doing?", and they boy replies, "Oh they are jump roping too." "Why don't we jump rope!" says the girl. So, they go behind a barn and the girl and boy starts to fuck. She then tugs at his balls and asks,"What are these?" The boy replies,"Knots." And the girl says, "Well, why don't you take out the knots so I can get more rope!
