People often ask me if I have ever been electrocuted. I always set them straight by explaining that electrocution is death. But yes I have been shocked. As an apprentice I learned how travelers on a 3way switch work the hard way. I was working on a 3way swich that I was informed was off. Lesson #1, always test first. I got hit off one traveler, so being the smart apprentice, I went and flipped the switch on the other 3way thinking I was turning it off, and promptly got shocked off the second traveler.
It was stupidity on my part and luckily we were all able to laugh about it later.
