Maybe a repeat but.......
On his 60th birthday, a man was given a gift certificate from his wife.
The certificate was for consultation with an Indian medicine man on a nearby reservation who was rumored to have a cure for erectile dysfunction.
When the husband went to the reservation, the old medicine man gave him a potion and, with a grip on his shoulder, warned 'This is a very 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 for as long as you want."
The man thanked the old Indian, and 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, took 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 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.
