A guy was walking on a beach when he found an old lamp. He rubbed it to get a better look at what he'd found. Pow, out pops a genie.
In typical fashion, if you've ever met a genie, the genie said "I will grant you three wishes, but your ex-wife will get double."
The man was shocked that the genie knew he had an ex-wife, but then again he was a genie.
After thinking for a while he said "I wish I had a mansion." The genie granted it, and of course his ex-wife got two mansions.
The man said "I would like a million pounds." The genie again granted it and his ex-wife got two million pounds.
Then the man said, "Scare me half to death."
