A patient suffering from a nasty cold visited Dr. D Costa and said groaning, "Doctor, can you cure my terrible cold? It has made things hell for me for the last four or five days".

Having never read about any confirmed cure for common cold, the young, over-zealous doctor advised after much initial hesitation, "You may do one thing. Take a hot bath and stand beneath a fan."

"Stand beneath a fan!" perplexed by the strange instruction, the patient asked, "Will your method cure me, doctor?"

"I can't say so for sure," replied Dr. D Costa, with his spectacles resting on his nose, "but if you do as directed, you are certain to get pneumonia which I can cure for sure!"
