A gas station owner in Arkansas was trying to increase his sales. So he put up a sign that read: "Free Sex with Fill-Up, just guess the right number between 1 and 10."
Soon a local red neck pulled in, filled his tank and asked for his Free Sex. The owner told him to pick a number from 1 to 10. If he guessed correctly, he would get his Free Sex. The red neck guessed 8, and the proprietor said, "You were close. The number was 7. Sorry. No Free Sex this time."
A week later, the same red neck, along with his brother, Bubba, pulled in for another fill-up. Again he asked for his Free Sex. The proprietor again gave him the same story, and asked him to guess the correct number. The red neck guessed 2 this time. The proprietor said, "Sorry, it was 3. You were close, but no Free Sex this time."
As they were driving away, the red neck said to his brother, "I think that game is rigged, and he doesn't really give away Free Sex."
Bubba replied, "No it ain't, Billy Ray. It ain't rigged. My wife won twice last week!!”
