Against his better judgment, the auto garage hired three blondes when he was in need of a couple of mechanic's helpers. Taking great pains to be specific, he explained to the three that he wanted them to clean a car that was parked outside. He gave them two extension cords, the vacuum cleaner, a bucket, rags and the car keys.
Later he went out and discovered them sitting in the car, feet up on the dashboard, listening to the stereo.
"Why aren't you vacuuming the car?" he asked.
"Because the extension cord wouldn't reach," was the reply.
Exasperated, he said, "That's why I gave you two."
"Well duh, we tried the other one!" one blond said. "It wouldn't reach neither."
