Rope

There was a nun who wanted to marry a farmer boy. One day she went to his parent's house for dinner. When they got done eating dinner, they decided to go for a walk through the pasture. While they were walking they came upon these two horses that were mating. She looks at them with wonder because she's never seen anything like this before so she asks the boy, "What are they doing?"

He says, "They are making love."

"Well, what's that long thing he's sticking in there?" She ask.

"Oh uh that's his rope", he answered.

"Well what are those two round things on the other end?" She ask.

He says, those are his knots".

She says, "Oh OK I got it."

As they continue their stroll, they come to a barn and go in. She looks at him and says "I want you to make love to me the way those animals were."

Surprise and excited he agrees. While they're getting all hot and heavy, she grabs his balls and squeezes.

"Whoa, whoa whoa, what are you doing ?" He shouts.

She innocently replies, I'm untying the knots so I'll get more rope"
