Joe was talking to his buddy at the bar, 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 that's what Joe did.

The next day at the bar his buddy said,
"Well? Did you take my suggestion?"

"Yes, I did," said Joe.

"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!!"
