Murphy applied for an engineering position at an Irish firm based in Dublin. An American applied for the same job, and both applicants, having the same qualifications, were asked to take a test by the department manager. Upon completion of the test, both men had only missed one of the questions on the test. All the other questions were answered correctly. The manager went to Murphy and said, "Thanks to both of you for your interest, but we've decided to give the American the job." Murphy said, "And why would you be doing that? We both got 9 questions correct. This being Ireland and me being Irish, I should get the job!" The manager replied, "We have made our decision not on the correct answers, but on the question you missed." "And just how would one incorrect answer be better than the other?" asked Murphy. The manager replied, "Simple. The American put down for question five, 'I don't know.' You put down, 'Neither do I.'"
