DON’T DAMAGE ITS fragile metal ego: “If you are a piece of steel, I implore you not to watch the YouTube clip. If you are in the room with a piece of steel, divert its attention, send it out of the room for ice cream, do what you can to insure it doesn’t see this. The clip shows a steel bar being turned down like it was soft butter being cut by a hot knife. It is humilating if you’re a piece of steel. It makes you look like a piece of free-machining aluminum.”
