A guy and his girl went camping.

While taking a walk through
the woods they came upon two rabbits making love.

The girl asked
"What are they doing?"

To which her boyfriend answered "Ropin'."

A short while later they came upon two deers having sex.

The
girl asked "Are they ROPIN' too?"

To which her boyfriend answered
"Yup."

Later that night, back at the campsite, the girl said "I'm
tired, I think I'll turn in."

Her boyfriend said "I'm tired too.
Would you like to try ROPIN'?"

The girlfriend said "Yes very much,
but I wasn't sure how to ask you."

They went into the tent, got undressed and started having sex
in the doggie style position, just as the animals they saw were
doing.

After a few minutes, the boyfriend felt his girlfriends
fingers on his balls.

"What are you doing?" he asked.

To which she replied "Trying to
untie this knot, I need more rope!"
