Two men are standing at the base of a flagpole, looking up. A blonde walks by and asks them what they are doing. One tells her, "We're supposed to be finding the height of this flagpole, but we don't have a ladder."
The blonde takes out an adjustable wrench from her handbag, loosens a few bolts and lays the flagpole down. Then she takes out a tape measure, measures the pole, and tells them that it's 18 feet 6 inches. Then she walks off.
One man says to the other, "Isn't that just like a blonde! We need the height and she gives us the length."
