Scott and Glenn were trying to measure a telephone pole. Every time one of them would get part way up, he would slide back down.
Then along came this really big, muscular guy who asked, "Hey, what are you guys doing?"
Scott replies, "We're trying to measure the height of this pole."
The muscular guy 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 and tells them, "40 feet," then walks away.
Glenn turns to Scott and says, "What a stupid idiot—we wanted the height, not the width."
