Never end a sentence with a preposition

After being persuaded, I drove to see him, handed my ticket to the wise 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 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 very 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 was the 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
