A woman brought her baby in to see the doctor, and he determined right
away the baby had an earache.
He wrote a prescription for eardrops. In the directions he wrote, "Put
two drops in right ear every four hours" and he abbreviated "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 eardrops and sure enough, the
pharmacist had typed the following instructions on the label:
"Put two drops in R ear every four hours."

My mother works in a hospital as a registrated nurse and everybody at her work would tease me when I was a little girl (even up to today) that I would become a doctor because my signature is totally incoherent... (thinking about the nice & fat paycheck if i work as a doctor) hmm.. I could try it out-- at least I got my signature all ready! 
Thank god I did not do that to my boys when they had ear infections.
