The LOC Metric
I used to think the same thing whenever a Mangler mentioned the LOC metric. At one point in time my LOC was being measured in the negative hundreds of LOC a day, when I was rewriting the dumbass code that had been written when LOC was king.
My attitude had always been to avoid the 'M' word (metric), cos as soon as you introduce one your employees will stop doing real work, and just start working the metric.
