A university committee was selecting a new dean. They had narrowed the candidates to a mathematician, an economist, and a lawyer.

The economist thought for several minutes and finally answered, “Four, plus or minus one.”
Finally, the lawyer stood up, peered around the room, and motioned silently for the committee members to gather close to him. He replied in a calm, conspiratorial tone, “How much do you want it to be?”
