Today at work, since we have to work Easter Monday, a lot of people left early. I had to stay.
The crazy guy had been running one of the CNC machines, but it hadn't finished its cycle by the time he was ready to leave, so he told me to turn it off when it was finished. He pointed to a red button and said, "Just push this button. You don't have to zero the machine or anything. Actually, if you zero it, the machine will tear itself apart." He looked at the keypad on the machine and then pointed to a key (presumably the one you press to zero the machine). "Don't press this key." Then he left.
Of course, after that, all I could think of doing was pressing that key.
