What is that they say about things coming in threes?

Today's customer was accompanied by her ex-husband .... a former NASA engineer. It seems that the house they just bought, and are remodeling, had some 'electrical problems."

It was a pleasantly easy job; tighten one wire nut and reset one breaker, and all was happy. My high-tech tool for troubleshooting? A rolls of red and green masking taps. Working receptacles got a piece of green, troubles got the red. It was quite easy then to see the 'pattern,' and zero in on the bad box laugh
