A blonde called an import parts warehouse and asked for a 28 ounce water pump.
"A what?" said the confused parts guy.
"My husband says he needs a 28 ounce water pump."
"A 28 ounce water pump? What kind of car does it fit?"
As the parts guy wrote down "Datsun, 28 ounce water pump" the light in his head went on. "Oh yes ma'am. We've got 28 ounce water pumps. We have 24 ounce and 26 ounce water pumps, too."
"Finally, " she said. "You're the first place I've called that knew what I was talking about."
"Yes ma'am. That's because we're a full-service parts warehouse; it's our job to have the parts you need, like a 28 ounce water pump," he said.
(the other places must have been staffed wit hlow information voters)
