The person from personnel who interviewed him, asked various questions about him and his education, but then stumped him by asking, “What is three times seven?”
“22”, Rick replied.
After he left the interview, he double-checked the answer on his calculator, discovered his error and realized that there was no way that he would get the job.
About two weeks later, imagine his surprise when he got a letter that said he was hired for the job!
Well, Rick was not one to look a gift horse in the mouth, but knowing that he had got the wrong answer, he 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”.
