RAY: This was sent in by Tom Downs. He says, "The other day I was in the local auto parts store and a teenage boy came in and said, 'I want a 710 cap.'

"Everyone looked at one another. The parts manager asked, 'A 710 cap, what's that?'

"The kid said, 'You know, it's right on the engine. I lost mine.'

"The manager replied, 'Well, what does it do?'

"The kid said, 'I don't know what it does. I'm a new driver and my father made me promise that every time I drive the car, I open the hood and look around underneath to make sure that the belts look all right, the fluids are full and the hoses are okay. And the other day, I noticed that this 710 cap was missing and I needed a new one.'

"'What kind of a car is it?' the fellow behind the counter asked, thinking perhaps he'd luck out and the car would be an old Datsun 710.

"The kid said, 'It's a Buick.'

"The parts manager asked, 'How big is this part?' And the kid made a circle with his hands that was about three inches in diameter.

"Finally, the manager asked, 'Can you draw me a picture?' The kid drew a cap and wrote 710 on it. While he was drawing it, I was looking over his shoulder and I had no clue what the part is. But the guy behind the counter stifled a laugh and said, 'I know exactly what you want.'"

Think you know what part the kid needed?

Answer:
RAY: And the question is what did the kid want?"

TOM: A dope slap.

RAY: Well, you could do the same thing yourself. You could draw a circle that was three inches in diameter and you could write 710 in it and then pretend you're the counter guy by turning the thing 180 degrees, and you want an oil cap.
