Humour is for enjoyment

My family physician told me of an incident that
actually happened to him back in the early days
of his practice. He said a woman brought her baby
to see him, and he determined right away that the
baby had an earache. He wrote a prescription for
ear drops. In the directions he wrote, "Put two
drops in right ear every four hours" abbreviating
"right" as an R with a circle around it.
Several days passed, and the woman returned with
her baby, complaining that the baby still had an
earache, and his little behind was getting really
greasy with all those drops of oil.
The doctor looked at the bottle of ear drops and
sure enough, the pharmacist had typed the
instructions on the label as: "Put two drops in
R ear every four hours."
