Two Arkansans drove to a gas station in Texas for gas because they heard about a contest being offered to customers who purchase a full tank of gas. When they entered the gas station to pay, they asked the attendant about the contest.

"If you win the contest, you're entitled to receive free sex," said the attendant.

"How do we enter?" asked the Arkansan.

"Well, I'm thinking of a number between 1 and 20. If you guess correctly, you win free sex."

"O.K. I guess 14," said the Arkansan

"Sorry, I was thinking of 16," replied the attendant.

The following week, the two Arkansans returned to the same gas station to fill'er up. When they went to pay, one Arkansan asked the attendant if the contest was still running.

"Of Course," replied the attendant. "I'm thinking of a number between 1 and 20. If you guess right, you win free sex. "

"Four," said the Arkansan.

"Sorry, I was thinking of 6," replied the attendant. "Come back and try again soon."

As the Arkansans returned to their car, the first Arkansan said to the other, "You know, I'm beginning to think this contest is fixed."

"Don't think so," said the other Arkansan. "My wife won last week."
