Billy Ray and Uncle Chester were driving through the hills of Tennessee when they saw a
sign that said, "FREE SEX WITH FILL UP".
Of course this grabbed their attention and they decided to stop for gas.
"What'll it be?" asked the attendant.
"Fill It UP!!!" replied Uncle Chester.
After filling the tank the attendant replied, "That'll be $12.50..."
"What about that free sex?" asked Billy Ray.
"You'll have to play a game first.", replied the attendant, "I'll think of a
number between 1 and 10 then you tell me what it is."
"Alright", says Billy Ray, "...Four".
"Sorry, it was seven", said the attendant.
"Let me try", said Uncle Chester, "...six."
"No, I already told ya it was seven," replied the attendant.
Billy and Uncle Chester drove away disappointed at their lack of fortune.
After several moments of solitude Uncle Chester spoke up, "You know there wasn't any free
sex back there... it was all just a hoax."
"Don't be so sure", replied Billy Ray, "My wife went in there and won twice last week!"
