A well known, rich business man's wife broke her hip. The business man got the best orthopedic surgeon in town to do the operation, which consisted of lining up the broken hip and putting in a screw to secure it.

The operation went smoothly, and the doctor sent the business man a bill for $5,000 for his services. The business man, outraged at the high price, sent the doctor a letter demanding an itemized list of the costs. The doctor responded to the letter with the following:

1 Screw: $1.00
Knowing how to put it in: $4,999
Total: $5,000

The business man never argued.
