Rich, Dave and Johnny are three contractors...

...who are bidding to fix a broken fence at the White House. All three go with a White House official to examine the fence.

Rich first 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."

Dave 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."

Johnny 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?"

Johnny whispers back, "$1000 for me, $1000 for you, and we hire the other guy to fix the fence for $700."
