On his 74th birthday, a man got a gift certificate from his wife.
The certificate paid for a visit to a Cherokee medicine man living on a nearby reservation who was rumored to have a wonderful cure for erectile dysfunction. After being persuaded, he drove to the reservation, he handed his ticket to the medicine man, and wondered what he was in for.
The old man slowly, methodically produced a potion, handed it to him, and with a grip on his shoulder, warned, 'This is a 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."
The man was encouraged. As he walked away, he turned and asked, "How do I stop the medicine from working?"
"Your partner must say '1-2-3-4,'" the Medicine Man responded, "but when she does,the medicine will not work again until the next full moon."
He was very eager to see if it worked so he went home, showered, shaved,took a spoonful of the medicine, and then invited his wife to join him in the bedroom. When she came in, he took off his clothes and said, " 1-2-3!"
Immediately, he was the manliest of men. His 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, because we could end up with a dangling participle.
