Heads Up! (pun intended). Warning: Sexual Content

An AOA cautionary tale:     For his 75th birthday, a man received a gift certificate from his wife. The certificate paid for a visit to a shaman living on a nearby reservation who was rumored to have a wonderful cure for erectile dysfunction.     He drove to the reservation, handed his certificate to the medicine man and wondered what he was in for.     The old shaman slowly, methodically produced a potion, handed it to him, and with a grip on his 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."     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', but when she does, the medicine will not work again until the next full moon."     The old gent 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, excited, began throwing off her clothes. Then she asked, "What was the 1-2-3 for?"   And that is why we should never end our sentences with a preposition: we could end up with a dangling participle. Thanks to CS.
