Murphy, an Irishman, was applying for an engineering position at an Irish firm based in Dublin. Jones, an American was applying for the same job. 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, "Thank you for your interest, but we've decided to give Jones the job."
"Why?" Murphy protested. "We both got nine 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 both missed."
"And just how would one incorrect answer be better than the other?" Murphy asked.
"Simple," the manager replied. "The answer Jones put down for question number 5 was, 'I don't know.' You put down, 'Neither do I.' "
