Per Smitty Two:
It is almost impossible to electrocute yourself accidentally with 120
volts. Mythbusters couldn't even kill a crash test dummy by throwing a
hair dryer or radio into the bathtub.

When I was an electronics tech in the military, the story they
told us was that the most effective way to electrocute ones' self
was to establish a path through the chest cavity - as in grasping
a grounded beam or something for support with one hand while
reaching into someplace with hot wires with another.

This would seem to differ significantly from the MythBusters
scenario.
