Three contractors are bidding to fix a broken fence at the Rhode Island Statehouse in Providence. One is from Cranston, another from North Kingstown and the third from Exeter. They go with a Statehouse official to examine the fence.

The North Kingstown 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 Exeter contractor also does some measuring and figuring, and then says "I can do this job for $700: $300 for materials, $300 for my crew and $100 profit for me."

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

The official, incredulous, says, "You didn't even measure! How did you come up with such a high figure?"

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

"She sells candy," the boy said.
