An accountant answered an advertisement for a top job with a large firm. At the end of the interview, the chairman said, “One last question – what is three times seven?”

The accountant thought for a moment and replied, “Twenty-two.”

Outside he checked himself on his calculator and concluded he had lost the job. But two weeks later he was offered the position. He asked the chairman why he had been appointed when he had given the wrong answer.

“You were the closest,” the chairman replied.
