Santa used to work in a saw-mill. He was in hospital after he lost his arm in an accident.

Banta was visiting him in the hospital.

Banta, "It was really bad that you lost your hand. However thank God that it was your left hand, since you are right handed."

Santa, "It is also because of my quick thinking. Actually it was the right hand which was going to be caught in the machine. Then I realised that I am right handed and so switched hands just in time!
