A guy finds an old lamp

A guy is walking along a beach and finds an old lamp.

He rubs it, and a genie pops out. The genie says, “I can grant you three wishes, but there’s a catch: your ex-wife gets double whatever you ask for.”

The man thinks and says, “For my first wish, I’d like a billion dollars.”

The genie snaps his fingers. “Done. You have a billion dollars, and your ex-wife has two billion.”

The man says, “For my second wish, I’d like a fleet of the world’s finest sports cars.”

The genie snaps his fingers. “Done. You have ten Ferraris, and your ex-wife has twenty.”

The man pauses, looking very thoughtful. Finally, he says, “For my third wish… I’d like to donate one of my kidneys.”
