The famous ice breaker

One of the famous icebreakers used in B schools .. . i have heard different versions of this one atleast 3 times in the last one month :)

A CEO was interviewing candidates for his firm and decided to ask the same question "What is 2+2" to all of them
The engineer pulled out his slide rule and shuffled it back and forth, and finally announced, "It lies between 3.98 and 4.02".
The physicist declared, "It's in the magnitude of 1x10 power 1."
The social worker said, "I don't know the answer, but I am glad that we discussed this important question.
The accountant looked at the business owner, then got out of his chair, went to see if anyone was listening at the door and pulled the drapes. Then he returned to the business owner, leaned across the desk and said in a low voice, "What would you like it to be?" :D
