There were two men who went into a company to apply for the same job in a factory in Dublin, Ireland. One was an Irishman and the other was an Irish-American.
The supervisor said, "I'm going to give both of you a test. Whoever gets the best score on the test will get the job."
The two men went off to another room to take the test.
The supervisor collected the tests when each man finished. He went over them then called the men into his office one at a time.
When he talked to the native Irishman he said, "I'm afraid I had to give the job to the Yank."
The native Irishman replied, "I can't believe it! I'm from this country. I should have the best chance. What makes him have a better chance?"
The supervisor explained, "Well, on question #28 the Yank wrote down, 'I don't know,' and you wrote down on your test, 'I don't know either!'"
