Luke and Scooter stopped at a gas station to fill up their truck. On the side of the building, they saw a sign saying "ENTER HERE FOR A CHANCE AT FREE SEX!" They hurried inside and asked the attendant how to enter.
"All you gotta do," said the attendant, "is guess a number between 1 and 10"
"Okay," said Luke. "Five"
"Sorry," said the attendant. "The number was eight."
Scooter stepped up next to try his luck.
"Seven," he guessed.
"Sorry," said the attendant. "The number was three."
The two got back into their truck and drove away. As the sped down the road, Scooter turned to Luke and said, "You know, I think that contest was rigged."
"Nope, it's on the up and up," said Luke. "Last week, my wife won twice."
