When I was hauling iron, I hauled a D-7 dozer up into the mountains. It was kind of a payola deal. The boss sent me, and an operating engineer up to build an oilfield honcho a building pad for a home he was planning on building. Easy run for me, I took along some rags and polish to shine up my ride and kill the time while the operator was building the pad. The honcho had a huge something on his face that was I don't know a big purple birthmark or something it covered his balding scalp and part of his forehead. Okay, the boss really bears down on me, and says whatever you do, don't say a word about this guy's birthmark for want of a better term. We get there, the boss is there, the honcho is there, the operator is there, I unload the dozer, and walk over to where they are shooting the layout of the pad. Just then, the operator looks over at the honcho, and asks; By the way, what the hell happened to your head? I just kind of stood back and watched as my boss tried to shrink down into his boots as the honcho's face turned bright red! The operator completely unperturbed climbed up in the seat of the dozer and went to work.
