Illustration- Time, Speed, Dentists
The little boy was afraid of the dentist, so his dad decided to set the example and have his teeth examined, too. The dentist looked inside the father’s mouth & said, "There’s a tooth there that has to be pulled."
The father asked, "How much will it cost?" The dentist answered, "We charge $50 a tooth." Then the father asked, "How long will it take to actually pull the tooth?" The dentist answered, "About a minute."
The father protested, "I get paid by the hour, and when I think of paying $50 for a minute’s work, that is a terribly high hourly wage."
"Well," the dentist said, "I can pull the tooth more slowly if you like."
