Down-Hearted

   I am Dr. Vincent. I just had a patient run in.  He was turning blue and all the doctors said he was not breathing. Then I said “He has to be breathing because if he wasn't he would be dead.”  Then all the doctors said, "You are right, Dr. Vincent!" All the doctors were thinking very hard. Then Dr. James said, “Maybe we should operate on his heart.” All the doctors agreed.
    During the operation we could not find the heart for some reason.  It seemed to have fallen down. After the operation it was obvious that he had severe case of down-hearted. All the doctors were saying that the diagnosis was that. The question was how were we to bring the heart back up? First of all, we have to find out why his heart fell down. We all were thinking very hard. Finally Dr. Kyle said, "He is sad."  All the doctors said that was correct.
    First we tried to pick it up and that did not work. Then we tried to hang the heart from string. That also did not work. Finally, Dr. Mike said, "He has down-heart, right?"  The doctors said, "Then, let’s make him happy!”. All the doctors decided to think happy dreams to the patient and that worked very well.
