Two men drove to a gas
station for a fill-up because they heard about a contest being offered by the station to
patrons who purchase 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 the first man.

    "Well, I'm thinking of
a number between 1-10, if you guess right, you win free sex."

    "O.K. I guess 7,
" said the first man.

    "Sorry, I was thinking
of 8," replied the attendant.

"Come back soon and try again"

    The next week, the two men
returned to the same station to get gas. When they went inside to pay, the second man
asked the attendant if the contest was still going on.

    "Sure," replied
the attendant. "I'm thinking of a number between 1-10, if you guess right. You win
free sex."

    "2" said the
second man

    "Sorry, I was thinking
of 3," replied the attendant. "Come back soon and try again."

    As they walked back to the
car, the first man said to the second man,"You know, I'm beginning to think this
contest is rigged."

    "No way," said
the second man. "My wife won twice last week."
