On his 84th birthday, Moshe gets given a gift certificate from his wife Ruth. The certificate is for a free appointment with Dr Chan, an unlicensed Chinese doctor practicing illegally in London, but who is rumored to have a wonderful cure for erectile dysfunction.
After much discussion, Ruth finally persuades Moshe to go see this doctor and the next day he drives to the doctor’s address.
After a short chat, Dr Chan hands Moshe a potion and says, “This powerful medicine. You take only one teaspoonful and say aloud, ‘1-2-3.’ When do this, you become more manly than been before and can perform long as want.”
Moshe is delighted to hear this. But before he leaves, Moshe asks Doctor Chan, “How do I stop the medicine from working?”
Dr Chan replies, “Your partner must say, ‘1-2-3-4.’ When do this, medicine not work again until next full moon.”
Very eager to see if it works, Moshe returns home, showers, shaves, takes a spoonful of the medicine, and then invites Ruth to join him in the bedroom.
As soon as she enters, he takes off his clothes and loudly says, “1-2-3.” Immediately, he was the manliest of men. Ruth is excited to see this and throws off her clothes. She then asks Moshe, “What was the 1-2-3 for?”
AND THAT, LADIES AND GENTLEMEN, IS WHY WE SHOULD NEVER END OUR SENTENCES WITH A PREPOSITION, BECAUSE WE COULD END UP WITH A DANGLING PARTICIPLE.
