A gas station owner was trying to increase his sales, so he put up a sign that read,
“Free Sex with Every Fill-Up.”
Rob pulled in, filled his tank and asked for his free sex.
The owner told him to pick a number from 1 to 10, and said that if he guessed correctly, he would get his free sex.
Rob said “today is my birthday, i’m feeling LUCKY and I guess 8”.
The owner said, “You were very close, the lucky number was 7.
Sorry, no sex this time.
”A week later, Rob, with his friend Marvin, pulled in for another fill-up.
Again Rob asked for his free sex.
The proprietor again gave him the same story, and asked him to guess the correct number.
Rob guessed 2.
The proprietor said, “Sorry, it was 3, you were very close, but no free sex this time.
”As they were driving away, Marvin said to Rob,
“I think that game is rigged and he doesn’t really give away free sex at all.
”Rob replied, “No it’s genuine enough Marvin.
My wife won twice last week.”
