wo men were trying to measure a telephone pole. They kept trying to climb it and kept sliding down. Along came a big, musclebound man who asks, "Hey, what are you guys doing?"
The two men say, "We're trying to measure the height of this pole."
The strong man wraps his arms around the pole, pulls it out of the ground, lays it down and measures it. Then he picks it up, puts it back in the ground, says "40 feet" and walks away.
The first man says to the other, "What a stupid fool - we wanted the height, not the length."
