A guy finds an old lamp on the beach. He rubs it and a genie appears. The genie informs the guy that he will grant him three wishes, but whatever he wishes for his ex-wife will get twice as much.
"How about $1 million?" he asks. "Your ex-wife now has $2 million in her account as well," says the genie. "I've always wanted a Benz, how about that?," he asks. "Your ex-wife now has two of those cars," says the genie. The guy stopped to think for a minute, knowing that he had only one wish left.
"Could you beat me half to death?"
