Two students were standing at the base of a flagpole, looking up.
Flip walked by and asked what they were doing.
“We’re supposed to find the height of the flagpole”, said one, “But we don’t have a ladder.”
Flip: Hand me that wrench out of your toolbox.
He loosened a few bolts, then laid the pole down. He then took the measuring tape from their toolbox, took the measurement and announced, “Eighteen feet, six inches” and walked away.
The second engineer shook his head and laughed and said – We needed the height, and he gave us the length!
