Two bikers rode into a gas station in Indiana for a fill-up, because they heard about a contest being offered by the station to patrons who purchased a full tank of gas. When they went inside to pay, the men asked the attendant about the contest. "If you win, you're entitled to free sex" said the attendant.
"How do we enter?" asked one biker.
"Well, I'm thinking of a number between 1 and 10, if you guess right, you win free sex."
"OK. I guess 7," said the other rider.
"Sorry, I was thinking of 8," replied the attendant. The next week, the two guys go back to the same station to get gas. When they went inside to pay, the one asked the attendant if the contest was still going on. "Sure," replied the attendant. "I'm thinking of a number between 1 and 10, if you guess right. You win free sex."
"2" said the Harley rider.
"Sorry, I was thinking of 3," replied the attendant. "Y'all come back soon and try again."
As they walked back to their bikes, one said to the other, "You know, I'm beginning to think this contest is rigged." "No, I assure you it isn’t," came the reply. "My wife won twice last week."
