"The farmland gas station" joke

John and Cathy were driving through Arkansas farmlands on their way from New York to California. Looking at his fuel
gauge, John decided to stop at the next gas station and fill up. About five minutes later, he spotted one and pulled over to the
high octane pump.
"What can I do fer y'all?," asks the attendant.
"Fill her up with high-test," replied John.
While the attendant was filling up the tank, he started checking out the car. "What kind of car is dat?" he asked, ". . . never
seen one like it b'fore." "Well," responded John, his chest swelling up with pride, "This, my boy, is a 1997 Mercedes Benz."
"What all does it got in it?" asked the attendant. "It has everything," John said. "It has power steering, power seats, power
sun roof, power mirrors, AM/FM radio with a 10-deck CD player, 8-speaker stereo, disks brakes all around, leather interior,
digital instrument package and, best of all, an 8. 8 V12 engine."
"Wow," said the attendant, "That's really somethin'."
"How much do I owe you for gasoline?" asked John.
"That'll be $30. 17." said the attendant.
John pulled out his money clip and peeled off a twenty and a ten, then goes into his other pocket and pulls out a handful of
change. Mixed up with the change are golf tees. "What dem little wooden things." asked the attendant. "That's what I put my
balls on when I drive." said John. "WOW!" said the attendant, "dem Mercedes people think of everything!"
