A Yankee applied for the same job and both applicants having the same
qualifications were asked to take a test by the manager. Upon
completion of the test, both men only missed one of the questions.
The manager went to Bubba and said: "Thank you for your interest but
we've decided to give the Yankee the job."
Bubba asked: "And why are you giving him the job? We both got nine
questions correct; this being Louisiana, and me being a Southern boy I
should get the job!"
The manager said: "We have made our decision not on the correct
answers, but rather on the one question that you both missed."
Bubba then asked: "And just how would one incorrect answer be better
than the other?" The manager replied: "Bubba, it's like this... on
question #4, the Yankee put down, "I don't know." And you put down,
"Neither do I."
