An Irish petrol station was trying to increase it's sales so the owner put up a sign saying "Free Sex with every tank of petrol." Soon Paddy pulls in, fills his tank, and then asks for his free sex. The owner told him pick a number from (1) to (10), if he guessed correctly, he would get his Free sex. Paddy then guessed (8), the proprietor said, "You were close. The number was (7). Sorry, no sex this time." A week later Paddy, along with his pal Mick, pulled in for a 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, again the proprietor said, "Sorry, it was (3). You were close, but no free sex this time." As they were driving away, Paddy says to Mick "I think that game is rigged and he doesn't really give away free sex." Mick replied, "No it isn't Paddy, it's not rigged -- my wife won twice last week."
