Answering an advertisement in a newspaper stating, "The Secret of Never Losing Another Game in Tennis for only $99.95" offered by the only "undefeated" tennis player alive, a young man cut out the reply address form, filled out his name and address, wrote out a check for $99.95, enclosed the reply address form and check into an envelope, and wrote the mailing address on envelope to a Post Office Box in Chicago, Illinois, stamped the envelope and placed the envelop in the mail.    

Reading the advertisements in the back of a tennis magazine, an advertisement caught a young man's attention: "The Secret of Never Losing Another Game in Tennis," offered by the only "undefeated" tennis player alive.  

"This could be the answer I have been looking for!" he said to himself.  "Once I have the secret, I can stop reading all these magazines for best practices, stop working out each day, and stop my special high protein and low carbohydrate diet."

He quickly completed the application form, wrote out a check for $99.95, and placed both the application and check into an envelope.
