Grammer Lesson: On my 70th birthday, I got a gift certificate from my wife. The certificate paid for a visit to an Indian shaman living on a nearby reservation who was rumored to have a wonderfulcure for erectile dysfunction. After being persuaded by my wife, I drove to the reservation, handed my ticket to the shaman, and wondered. The old man slowly, methodically,produced a potion and handed it to me, then with a firm grip on my shoulder, warned, 'This is powerful medicine and it must be respected. You take only one teaspoonful and then say '1-2-3â€™ . When you do that, you will be more manly than you have ever been in your life, and you can perform as long as you want. ' I was very encouraged, and as he turned and started to walk away, I asked, 'How do I stop the medicine from working?' The shaman responded your partner must sayâ€™1-2-3-4â€™. He then added another warning, â€œ but when she does, the medicine will not work again until the next full moonâ€. I was eager to see if it worked, so I went home, showered, shaved, took a spoonful of the medicine, and then invited my wife to join me in the bedroom. When she came in, I took off my clothes and confidently said, ' 1-2-3' ,and immediately I was the manliest of men. She got so excited, she began peeling off her clothes, and then she asked, â€œ What was the â€˜ 1-2-3 â€™ for ?â€ And that, my friends, is another reason why we should not end our sentences with a preposition.
