A couple driving a VW pulls into a service (gas) station. She's asleep in the passenger seat. He tells the mechanic to get in the car, so he does. The guy starts rocking the car, and something's squeaking. The mechanic cocks his ear for a moment, then laughs.
He grabs an oil can and oils the lady's earring (she's still asleep). The last shot is the couple driving off, then the text "If only everything in life was made like a Volkswagen".
