A repairman came in to fix the new giant computer. Studying it for a moment, he took out a screwdriver and turned a small screw an eight of an inch to the right. The computer started to hum.
The repairman filled out a bill for 300.00 dollars and handed it to the company accountant. The accountant demanded that the bill be itemized. Three hundred dollars was bit much for such a simple repair. Taking another piece of paper, the repairman wrote out: "Turning screw eight of an inch to right---$.50. Knowing where to turn---$299.50."
