With Apologies to Mother-In-Laws Everywhere.

Be careful what you wish for.

While walking on the beach one morning, a man stubs his toe on something in the sand. Reaching down, he uncovers a brass lamp. Half jokingly he begins to rub it and asks if there was a Genie in there.
POOF! Out of the lamp appears a Genie. "I have been trapped in the lamp for many hundreds of years and now you have freed me", the Genie says. "As a reward I shall grant you three wishes, but beware, whatever I grant to you, I grant twice again to your wife's mother." 
"I don't care what you give that old hag," the man says. "O.K. first wish, I want ten million dollars."
"As you wish," said he Genie. "You have ten million dollars in your bank account, and your mother in-law has twenty million." 
"Let the mean old bag have the money, I've got mine," said the man happily.
"And for your next wish,sir?" asked the Genie.
"I would like ten acres of beachfront property, right here, with a twenty room mansion on it."
"So be it, and so shall your wife's mother have twenty acres next door with a forty room mansion," declared the Genie. 
"Wait, what? Right next door? Oh this is not going how I had hoped," said the now despondent man.  
"Your final wish, sir?" asked the Genie.
Thinking long and hard before answering, the man turns to the Genie and says, "I want you to beat me half to death."
