A gas station owner in Mississippi, aiming to boost sales, posted a sign: "Free Kisses with Fill-Up."
Soon, a local man pulled in, filled his tank, and requested his free kisses. The owner told him to pick a number from 1 to 10; a correct guess would win the prize. The man guessed 8. "You were close," said the proprietor. "The number was 7. Sorry, no kisses this time."
A week later, the same man returned with his friend Bubba for another fill-up and again asked for the free kisses. Once more, the owner asked him to guess the number. This time he guessed 2. "Sorry, it was 3," the proprietor replied. "You were close, but no free kisses this time."
As they drove away, the man said to his buddy, "I think that game is rigged. He doesn't really give away free kisses."
Bubba replied, "No it ain't, Billy Ray. It ain't rigged. My wife won twice last week."
