FW: How do you measure a flagpole

Two Irish blokes were standing at the base of a flagpole, looking up.
A blonde walked by and asked what they were doing.
Paddy: "We're supposed to find the height of this flagpole, but we don't have a ladder"
The blonde took a wrench from her purse, loosened a few bolts and laid the flagpole down. She then pulled a tape measure from her pocket, took a few measurements and announced that it was eighteen feet and six inches. She then walked off.

Mick: "Ain't that just like a blonde! We need the height and she gives us the length."
