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 only missed one of the questions. The manager went to Murphy and said.
Manager: "Thank you for your interest, but we've decided to give the American the job"
Murphy: "And why would you be doing that? We both got nine questions correct. This being Ireland and me being Irish I should get the job!"
Manager: "We have made our decisions not on the correct answers, but on the question you missed."
Murphy: "And just how would one incorrect answer be better than the other?"
Manager: "Simple, the American put down on question #5, "I don't know.", You put down "Neither do I."
