"Meet the Genie" joke

A couple was golfing one day on a very, very exclusive golf course, lined with million dollar houses. On the third tee the husband said, "Honey be very careful when you drive the ball-don't knock out any windows. It'll cost us a fortune to fix."
The wife teed up and shanked it right through the window of the biggest house on the course. The husband cringed and said, "I told you to watch out for the houses! Alright let's go up there, apologize, and see how much that's going to cost."
They walked up, knocked on the door, and heard a voice say, "Come on in." They opened the door and saw glass all over the floor and a broken bottle lying on its side on the foyer. A man on the couch said, "Are you the people that broke the window?"
"Uh yeah. Sorry about that," the husband replied. "No, actually I want to thank you. I'm a genie that was trapped for a thousand years in that bottle. You've released me. I'm allowed to grant three wishes - I'll give you each one wish, and I'll keep the last one for myself."
"OK great!" the husband said. "I want a million dollars a year for the rest of my life." No problem - it's the least I could do.
And you, what do you want?" the genie said, looking at the wife. "I want a house in every country of the world," she said. "Consider it done." the genie replied.
"And what's your wish genie?", the husband said.
"Well, since I have been trapped in that bottle, I havn't had sex with a woman in a thousand years. My wish is to sleep with your wife."
The husband looks at the wife and said, "Well we did get a lot of money and all those houses, honey. I guess it would be alright."
The genie took the wife upstairs, and ravished her for two hours.
After it was over, the genie rolled over, looked at the wife and said, "How old is your husband, anyway?"
"35." she replied.
"And he still believes in genies??? That's amazing!"
