Free sex with your fuel

Two Corntuckians went to a fuel station that was holding a contest:

A chance to win “Free Sex” when you filled your tank. They pumped their tanks and went to pay the attendant who said, I’m thinking of a number between 1 and 10, if you guess right you win free sex. Okay, agreed one, I guess seven. Sorry, I was thinking eight. replied the attendant.

The next week they tried again. When they went to pay, the attendant told them to pick a number. Two! said the second man. Sorry, it’s three, said the attendant, come back and try again.

As they walked out to their car, one redneck said to the other, I think this contest is rigged, No way, said his buddy, My wife won twice last week.
