Rick, 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?"
"22," Rick 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, he 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."
