A gas station in Mississippi was trying to increase it's sales so the owner > put up a sign saying "Free Sex with Fill-up."

Soon a local "redneck" pulled in, filled his tank, and then asked 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.
 The buyer then guessed (8), the proprietor said, "You were close. The  number was (7). Sorry, no sex this time."

 A week later, the same redneck, along with a buddy, Bubba, 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. The redneck 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, the redneck said to his buddy, "I think that game  is rigged and he doesn't really give away free sex."
 

Bubba replied, "No it ain't Billy Ray, it's not rigged -- my wife won twice  last week."
