Hiring an accountant

Kowalski, fresh out of accounting school, went to a interview for a good paying job. The company boss asked various questions about him and his education, but then asked him, "What is three times seven?" "Twenty-two," Kowalski replied.After he left, he double-checked it on his calculator (he knew he should have taken it to the interview!) and realized he wouldn't get the job.About two weeks later, he got a letter that said he was hired for the job! He was not one to look a gift horse in the mouth, but was still very curious.The next day, Kowalski went in and asked why he got the job, even though he got such a simple question wrong. The boss shrugged and said, "Well, you were the closest."
