Two blondes were standing at the base of a flagpole, looking up.
A construction worker walked by and asked what they were doing. “We’re supposed to find the height of the flagpole,” said the first, “but we don’t have a ladder.”.
He took a wrench from his tools-belt, loosened a few bolts, and laid the pole down. Then took a tape measure from his pocket, took a measurement and announced, “Eighteen feet, six inches,” and walked away.
The first blonde looked at the other and laughed. “What a stupid idiot! We ask for the height, and he gives us the length!”
