Three contractors are bidding to fix a broken fence at the White House in DC. 

One from New Jersey, another from Tennessee and the third, Florida. They go with a White House official to examine the fence. 

The Florida 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: $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: $300 for materials, $300 for my crew and $100 profit for me." 

The New Jersey 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 New Jersey contractor whispers back, "$1,000 for me, $1,000 for you, and we hire the guy from Tennessee to fix the fence." 

"Done!" replies the government official.
