What do think about this oldie?

An older Lao American man married to a young American wife. Since he is old, he finds that he is unable to satisfiy her. He went to see the doctors in the US but there was no cure and nothing seems to work. Finally, upon friends suggestion, he decided to go to Laos to see a Lao Herbal Medicine Man.

The Lao medicine man says, "I can cure this." With that said, he throws a white powder in a flame, and there is a flash with billowing blue smoke. Then he says, "This is powerful healing but you can only use it once a year. All you have to do is say '123,' and it shall rise for as long as you wish!"

The Lao American then asks, "What happens when it's over, and I don't want to continue?" The medicine man replies, "All you or your partner has to say is 1234, and it will go down. But be warned, it will not work again for another year."

He return home to America, anxious to try out his new powers and prowess. That night he is ready to surprise his wife. He showers, shaves, and puts on his most exotic shaving lotion and cologne. After he gets into bed and is lying next to her, he says, "123."

Suddenly, it is as if he was young again, just as the medicine man had promised. His wife, who had been facing away from him, turns over and asks, "What did you say 123 for?"
