I usually enjoy C.S.I. but there was an episode where a construction worker was killed.

Quote
(GRISSOM looks around and notices the drill hanging off the side of the floor.
He pulls it up.)

GRISSOM: Did this belong to Mr. Valenti

ROBERT HARRIS: Well, like I said he was the only one up here.

(GRISSOM examines the drill and notices that the metal housing is charred.)

GRISSOM: This drill is shorted out. Do you think he "jumped" before or after
he got the shock of his life?

ROBERT HARRIS: GFCI would have prevented shock.

SHERIFF BRIAN MOBLEY: What is GFCI?

ROBERT HARRIS: The Ground Fault Circuit Interrupter.

GRISSOM: Big words meaning you won't get electrocuted.

(GRISSOM grabs his kit and notices the outlet. He moves to examine the plug and
notices that the third prong of the plug is cut in half.)

ROBERT HARRIS: You see, if there's and electrical imbalance the GFCI trips the
circuit and the tools are suppose to shut itself off.

GRISSOM: But if the third prong of the plug is compromised, the interrupter
won't work. Will it, Bob?

ROBERT HARRIS: The third prong grounds the drill. Without it, the
interrupter's useless.

GRISSOM: These prongs don't usually snap off by themselves.

Once they said "The third prong grounds the drill. Without it, the
interrupter's useless." I had to watch something else. [Linked Image]
