A gas station out in the boondocks was trying to increase its sales, so the owner put up a sign saying, "Free Sex with Fill-Up".
Soon a local yokel pulled in, filled his tank, and then 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 guy guessed 8, and the proprietor said, "You were close, the number was 7. Sorry, no sex this time."
A week later, the same guy, along with a buddy, Bubba, pulled in for a 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 guy guessed 2 this time. Again the proprietor said, "Sorry, it was 3. You were close, but no free sex this time."
As they were driving away, the guy said to his buddy, "Bubba, 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."
