To address an emergency call a doctor came to see a rich patient at his home, who was screaming with extreme stomach pain and was surrounded by many anxious relatives. The Doctor kicked all the relatives out of the room, closed the door with patient and he inside.
After a while he came out and asked, "Please give me a pair of scissors." People gave him stainless steel scissors. He again went inside, closed the door and soon came back. He said, "Please give me a hammer." He got one. A number of times he repeated the routine of going inside, closing the door and then coming back again for a new tool.
Finally he came outside one more time and asked, "Please give me a screw driver." The oldest son could not stand it any more and lost his patience. In a crying voice he pleaded, "Doctor please tell us what has happened to our dear Dad. Will he live? Could we open his will?"
The doctor said, "No, I don't know that yet. I am still trying to open my stupid bag - I lost the key."
