Two Irishmen were standing at the base of a flagpole, looking up.
A blonde walks by and asks what they are doing.
Paddy: "We're supposed to find the height of this flagpole, but we
don't have a ladder." The blonde took a spanner from her handbag, loosened a few bolts and
laid the flagpole down. She pulled a tape measure from her pocket, took a
measurement from the base to the top whilst it was on the ground 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. :-)
