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?''
