A man went to see his doctor because
he was suffering from a miserable cold. His doctor prescribed some
pills, but they didn’t help.
On his next visit the doctor
gave him a shot, but that didn’t do any
good.
On his third
visit the doctor told the man, „Go home and take a hot
bath. As soon
as you finish bathing throw open all the windows and stand
in the
draft.“
„But doc,“ protested the patient, „if I do that, I’ll
get
pneumonia.“
„I know,“ said the doctor, „I can cure
pneumonia.“
