Bubba and Junior

Bubba and Junior were standing at the base of a flagpole.
A woman walked by and asked what they were doing.
"We're supposed to find the height of the flagpole," said Bubba, "but we don't have a ladder."
The woman took a wrench from her purse, loosened a few bolts, and laid the pole down. Then she took a tape measure from her packet, took a measurement, announce, "Eighteen feet, six inches,"
and walked away.
Junior shook his head and laughed, "Ain't that just like a dumb blonde. We ask for the height, and she gives us the length."
