A mathematician, an accountant and an economist apply for the same job.
The interviewer calls in the mathematician and asks "What does two plus two equal?" The mathematician replies "Four." The interviewer asks "Four, exactly?" The mathematician looks at the interviewer incredulously and says "Yes, four, exactly."
The interviewer then calls in the accountant : "What does two plus two equal?" The accountant says "On average, four -- give or take 10 percent."
Then the interviewer calls in the economist: "What does two plus two equal?" The economist gets up, locks the door, closes the shade, sits down next to the interviewer and asks "What do you want it to equal?"
