A gas station owner in Dublin was trying to increase his sales. So, he put up a sign that read, 'Free Sex with Fill-Up.'

Soon Brandon 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. Brandon guessed 8, and the proprietor said, 'You were close. The number was 7. Sorry. No sex this time.'

A week later, Brandon, along with his friend Mick, 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. Brandon 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, Mick said to Brandon, 'I think that game is rigged and he doesn't really give away free sex.'
Brandon replied, 'No it ain't, Mick. It's not rigged at all at all. My wife won twice last week.'
