Dr Goldberg....the miracle maker

Doctor Goldberg is known throughout London as one of the best consultants on arthritis. He always has a waiting room full of people who need his advice and specialist treatment. One day, Henry, an elderly gent, slowly struggles into his waiting room. He is completely bent over and leans heavily on his walking stick. A chair is found for him. Eventually, his turn comes to go into Doctor Goldberg’s office. Fifteen minutes later, to everyone’s surprise, he comes briskly out of his room walking almost upright. He is holding her head high and has a smile on his face. A woman in the waiting room says to Henry, "It's unbelievable, a miracle even. You walk in bent in half and now you walk out erect. What a fantastic doctor he is. Tell me, what did Doctor Goldberg do to you?"
"Miracle, huh miracle," says Henry, "he just gave me a longer walking stick!"
