Bubba and Cooter
Bubba and Cooter were standing at the base of a flagpole, looking up. A blonde lady 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 blonde woman took a wrench from her purse, loosened a few bolts, and laid the pole down; then she retrieved a tape measure from her pocket, took a measurement, announced, "Eighteen feet, six inches," and walked away.
Cooter shook his head and laughed. "Ain't that just like a dumb blonde? We asks for the height and she gives us the length !"
