In honor of International Women's Day, I need to repeat a blonde joke.

Two male construction workers in hard hats and coveralls were staring up at a very tall flag pole, with tape measures in hand, talking to each other. A pretty young blonde woman walked up and asked what they were discussing and whether she could help. They laughed at her and said that they were trying to figure out how to tell the height of the flag pole.

The blonde offered to help and they humored her. She asked if one of them had a wrench, and one was produced. She loosened the bolts on the flag pole and asked the construction workers to help her lower the pole to the ground. They did. The blonde pulled a tape measure out of her pocket and measured the length of the pole and wrote it down for the men.
Then, she helped them raise the pole, tightened the wrenches and walked away. The construction workers graciously thanked her.

When she was out of earshot, one man turned to the other and said, "Isn't that just like a blonde - not being able to tell the difference between length and height?"
