The Montana contractor takes out a tape measure and does some
measuring, then works some figures with a pencil.
"Well," he says, "I figure the job will run about $900. That's $400 for materials, $400 for my crew and $100 profit for me."

The Tennessee contractor also does some measuring and figuring, then says, "I can do this job for $700. That's $300 for materials, $300 for my crew and $100 profit for me."

The Chicago contractor doesn't measure or figure, but leans over to the White House official and whispers, "$2,700."

The official, incredulous, says, "You didn't even measure like the
other guys. How did you come up with such a high figure?"

The Chicago contractor whispers back, "$1000 for me, $1000 for you, and we hire the guy from Tennessee to fix the fence."

"Done!" replies the government official.
