"Free Sex with Fill-Up."

[Cuda-uk]

A petrol station owner in Dublin was trying to increase his sales. So,
he put up a sign that read, "Free Sex with Fill-Up." Soon Paddy 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. Paddy guessed 8, and the proprietor said, "You were close.
The number was 7. Sorry. No sex this time."

A week later, Paddy, 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. Paddy
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 Paddy, "I think that game is
rigged and he doesn't really give away free sex."

Paddy replied, "No it ain't, Mick.
It's not rigged at all at all. My wife won twice last week."
