A
petrol station owner in London was
trying to increase his sales.
So,
he put up a sign that read, 'Free Sex with Fill-Up.'
A local man
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 man guessed 8, and the proprietor
said, 'You were close. The number was
7. Sorry. No sex this time.'
A
week later, the man, 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. He
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 his mate, 'I think that game is
rigged and he
doesn't really give away free sex.'
The man replied, 'No it ain't,
Mick. It's not rigged at all. My wife won
twice last week.
