Its a cliche that there's no such thing as a dumb question; but you strain

My mother once couldn't get the vacuum to turn on, so she untied a knot in
the cord to make sure the electricity could get through. And then
admitted to doing it.

Back in the early days of electrification people were afraid the leave bulb
sockets empty because they thought the electricity would leak out like gas.
