Ollie and Nena: Roping

Ollie and Nena were driving down a country road. Nena sees two cats screwing on the side of the road.

"Ollie, Ollie, what are they doing?"
"Oh, they're roping Nena."

Further down Nena spots two dogs screwing on the side of the road. She points to them and asks,

"Ollie, what are they doing?"
"They're roping too Nena."

Later down the country road she sees two rabbits screwing on the side of the road.

"Ollie, are they roping?"
"Yeah, they are roping Nena."

With an innocent curiousity Nena turned to Ollie and asked, "Can we rope?"
"Ollie quickly jeered the car to the side of the road and jumped out.

In a nearby field Ollie and Nena strip down. (Ollie much quicker than Nena) Nena glances down and points to Ollies balls. "Ollie, what are those?" "Those are my knots Nena."

She sits and thinks real hard for a few seconds then responds, "So, if I untie the knots, do I get longer rope?"
