I saw electricians on the boat do some deliciously stupid stuff. Ever hear of a Megger? It's an ohmmeter made for measuring HUGE resistances, like the kind in industrial insulators. Millions of ohms. What it is is a little jack-in-the-box looking thing with two wires coming out one side, a crank on the other, and a meter movement in the middle. Used properly, you clip the probes at some distance from each other, turn the handle, and read the meter to measure the resistance.
Used improperly, you clip the electrodes to two rivets on a bare steel wall. One guy holds the megger while the other puts his hands against the wall. The first turns the crank, and the second holds on for dear life as he gets zapped with several thousand volts (at a tiny current, true, but still). Then they trade places. Lather, rinse, repeat until the shift is over or somebody thinks up something even dumber to do to pass the time.
Did they walk around afterward humming the "Pop Goes The Weasel" nursery rhyme?
