At the end of the tour, the guard asked them what they did for a living.  When they all replied that they were contractors the guard said, "Hey, we need one of the rear fences redone.  Why don't you guys take a look at it and give me a bid?"  So to the back fence they all went.

First to step up was the Florida contractor.  He took out his tape measure and pencil, did some measuring and said, "Well I figure the job will run about $900.  $400 for materials, $400 for my crew, and $100 profit for me."

Next was the Texas contractor.  He also took out his tape measure and pencil, did some quick figuring and said, "Looks like I can do this job for $700.  $300 for materials, $300 for my crew, and $100 profit for me."

Without so much as moving, the New York contractor said, "$2,700."

The guard, incredulous, looked at him and said, "You didn't even measure like the other guys!  How did you come up with such a high figure?" "Easy," he said. "$1,000 for me, $1,000 for you, and we hire the guy from Texas.
