Three programmers applied for a position at the Master. The Master asked each of them how many lines of code they produce daily. The first programmer proudly said "1000". The second programmer boasted "1200". The third programmer wispered she sometimes has "-100" lines on her tally.

The Master asked the student who he would hire. The second programmer, of course, the student replied.

The Master hired the third programmer, and the student was enlightened.
