SEX AND GOOD GRAMMAR - NUFF SAID...

On his 74th birthday, a man got a gift certificate from his
 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, he drove to the reservation, handed his ticket
to the medicine man and wondered what he was in for.
 The old man handed a potion to him, and with a grip on his shoulder,
warned, "This is a powerful medicine. You take only a teaspoonful and then say
 '1-2-3'.
 When you do, 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'," he 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.
