when my dad was 15 or so on his first day in a printshop his supervisor told him to go oil the press. So as he was oiling the press quite thoroughly with an oil can his supervisor told him to make sure and oil everything including around the switch. My dad said he didnt want to get to close to the electrical wiring. Nonsense, said the supervisor and grabbed the oilcan and started oiling around the switch whereupon he suddenly froze and got the strange expression on his face, his tongue was sticking out and his eyeballs popped. My dad thought the guy was taking the piss. Sure enough he pulled away and said, "no you dont want to oil there" and walked away. petr
