I bet most robotics and other embedded people have :) . I once got zapped because of a timer I set on a 50V section (95% of the board was 12V or less) of a circuit and proceeded to forget the timer (for a transistor switcher) was set in my debug version. It was just 50v DC and tiny amperage but still very zappy.
