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. 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 scissor." People gave him a stainless steel scissor. He again went inside, closed door and came back soon. He said, "Please give me a hammer." He got one. He repeated the routine of going inside, closing door and then coming back again for a new tool a few times.
He came outside one more time and asked, "Please give me a screw driver." With every of his requests for surgical tools the tension amongst the relatives was mounting high. The oldest son could not hold himself, broke down 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 damn bag, I lost the key."
