Oops, wrong number!
In this particular branch of the Army’s officer training school, the instructor was returning tests to the trainees. The students identified their work by the last four digits of their Social Security numbers. In the early hours of the morning, the instructor was calling out the numbers.
“Four-seven-seven-zero?” he asked.
“Here,” replied one half-awake lieutenant-to-be. Taking the paper, though, he realized he had mistakenly taken the wrong paper.
“Seven-zero-seven-five?” asked the instructor.
“Here,” repeated the student, gearing for trouble.
“I thought you were four-seven-seven-zero, Soldier,” spoke the teacher.
“That’s right, Sir,” answered the student, suddenly wide awake! “I have a nick-number.”
