Give Me Good News Doc

"Oh doctor, something is the matter with me, but I don't know what. I feel terrible, but I don't know how. And I have the most awful pain, but I don't know where." The doctor replied, "Well, I will prescribe something for you, but I don't know what. You will use it for three days, but I don't know how. It will cure you, but I don't know when."
