A man getting along in years finds that he is unable to perform sexually. He finally goes to his doctor who tries a few things, but nothing seems to work. So the doctor refers him to an American Indian medicine man.
The 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 guy 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."
The old gent rushes home, 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 cologne. Peeling off his underwear, he climbs naked into bed. Excitedly, he says to his wife, "123" ... and suddenly he has the most gigantic erection ever, just as the medicine man had promised.
His wife, who had been facing away from him, sleepily turns over and asks, "What did you say '123' for?"
