An English instructor tried to keep his students interested in correct grammar by relating his key points to situations the students could
appreciate.
"On my 65th birthday," he told his students, "I got a gift certificate from my wife. The certificate paid for a visit to a medicine man living on a nearby reservation who was rumored to have a wonderful cure for erectile dysfunction. After being persuaded, I drove to the reservation, handed my certificate to the medicine man, and wondered what would happen next.
"The old man slowly, methodically produced a potion, handed it to me, and with a grip on my shoulder, warned: 'This is powerful medicine and it must be respected. You take only a teaspoonful and then say 1-2-3. When you do that, you will become more manly than you have ever been in your life and you can perform as long as you want.'
"I was encouraged. As the medicine man walked away, I turned and asked, 'How do I stop the medicine from working?' 'Your partner must say 1-2-3-4,' he responded. 'But when she does that, the medicine will not work again until the next full moon.'
"I was eager to see if it worked. 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 said, '1-2-3!' Immediately, I was the manliest of men.
"My wife was excited and began throwing off her clothes. And then she asked, 'What was the 1-2-3 for?'
"And that, boys and girls, is why we should never end our sentences with a preposition."
