A guy was talking to his buddy, and he said,  "I don't know what
 to get my wife for her birthday - she has everything, and besides,
 she can afford to buy anything she wants, so I'm stumped."
 
 His buddy said, "I have an  idea - why don't you make up a
 certificate saying she can have 60 minutes of great sex, any way
 she wants it - she'll probably be thrilled." So the fellow did.
 
 The next day his buddy said, "Well? Did you take my suggestion?"
 
 "Yes, I did," said the fellow.
 
 "Did she like it?" His buddy asked.
 
 "Oh yes!  she jumped up , thanked me,  kissed me on the forehead
 and ran out the door, yelling "I'll be back in an hour!!"
