Audiophile Electrocution

On one of the company-sponsored discussion boards I read (for my brand of speakers), the head of the company is always warning us about power and how dangerous it is and how careful we must be. And we all read a lot of stern warnings about not opening up amps, about household wiring, licensed electricians and what not. I don't want to make light of this of this. But I am curious; do you know of any audiophiles who have been hurt or killed while tinkering with their systems? Have you been zapped?
