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."
