One day, a man was walking along the beach and came across an odd-looking bottle. Not being one to ignore tradition, he rubbed it and, much to his surprise, a Genie actually appeared.
"For releasing me from the bottle, I will grant you three wishes," said the Genie. The man was ecstatic. "But there's a catch," the Genie continued.
"What catch?" asked the man, eyeing the Genie suspiciously.
The Genie replied, "For each of your wishes, your neighbour will receive DOUBLE what you asked for."
"Hey, I can live with that! No problem!" replied the elated man.
"What is your first wish?" asked the Genie.
"Well, I've always wanted a Ferrari!"
POOF! A Ferrari appeared in front of the man. "Now, your neghbour has been given TWO Ferraris," said the Genie.
"What is your next wish?"
"I could really use a million dollars..." replied the man, and POOF!
One million dollars appeared at his feet. "Now, your neighbour is TWO million dollars richer," the Genie reminded the man.
"Well, that's okay, as long as I've got MY million," replied the man.
"And what is your final wish?" asked the Genie.
The man thought long and hard, and finally said, "Well, you know, I've always wanted to donate a kidney...."
