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 go as long as you want."
I was encouraged. As I 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, the medicine will not work again until the next full moon."
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 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 did you say 1-2-3 for?"
And that, boys and girls, is why we should never end our sentences with a preposition.
One could end up with a dangling participle.
