A fellow 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 that she wants it. She'll probably be thrilled."

So the fellow did.

The next day his buddy asked, "Well? Did you take my suggestion?"

"Yes, I did," said the fellow.

"...And 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!!!"
