"Round Of Golf" joke

A husband and wife were out enjoying a round of golf, and about to tee off on the third hole lined with beautiful homes.
The wife hit her shot and the ball began to slice - her shot was headed directly at a very large plate glass window. Much to her surprise, the ball smashed through the window and shattered it into a million pieces.
They felt compelled to see what damage was done and drove off to see what happened. When they peeked inside the house, they found no one there. The husband called out and no one answered. Upon further investigation, they saw a gentleman sitting on the couch witth a turban on his head.
The wife asked the man, "Do you live here?"
"No, someone just hit a ball through the window, knocked over the vase you see there, freeing me from that little bottle. I am so grateful!" he answered.
The wife asked "Are you a genie?"
"Oh, why yes i am. In fact, I am so grateful i will grant you two wishes, and the third i will keep for myself." the man replied.
The husband and wife agreed on two wishes - one was for a scratch handicap for the husband, to which the wife readily agreed. The other was for an income of $1, 000, 000 per year forever.
The genie nodded his head and said "Done!"
The genie now said, "For my wish, i would like to have my way with your wife. I have not been with a woman for many years, and after all, i made you a scratch golfer and a millionaire."
The husband and wife agreed.
After the genie and wife were finished, the genie asked the wife "How long have you been married?"
To which she responded "Three years."
The genie then asked "How old is your husband?"
To which she replied "31 years old"
The genie then asked "And how long has he believed in this genie stuff?"
