Two men applied for the same job

Two men applied for the same position. They had the same qualifications.

 In order to determine which to hire, the applicants were asked to take a test.

Both men missed only one of the questions. The manager said to the first applicant,

 “Thank you for your interest, but we’ve decided to give the job to the other applicant.”

“But why? We both answered 9 out of the 10 questions correctly,”

 said the rejected applicant.

“We based our decision not on the correct answers,

 but on the question you missed,” said the manager.

 “Your fellow applicant put down for #5,

‘I don’t know the answer.’

 You put down, ‘Neither do I.’
