A lawyer, an engineer and a mathematician were called in for a test. The engineer went in first and was asked: What is 2+2? The engineer thought awhile and finally answered: 4. Then the mathemetician was called in and was asked the same question. With little thought he replied: 4.0. Then the lawyer was called in, and was asked the same question. The lawyer answered even quicker than the mathematician: What do you want it to be?
