Two men are standing at the base of a flagpole, looking up.

A blonde asks them what their problem is.

They reply that they have been told to measure the height of the flagpole; they have a tape measure but no ladder.

The blonde steps forward, removes a bolt from the base of the pole, lowers it horizontal, takes the measure and tells them "It is 23 feet" and walks away.

One man turns to the other and says
"Stupid blonde. We ask for the height and she gives us the length".
