"Yong Man" joke

Young man 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, "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 9 questions correct. This being Ireland
and me being Irish I should get the job!"
Manager: "We have made our decision 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 ".
