When I was teaching high school electricity the students had to do a project. One of them wanted to make an electrified toilet seat. Being the open minded person I am I said, sure, go for it. The kid ran hot & neutral under the seat, drilled a hole in each side of the seat an pushed a bare wire thru each. He even put a bit of paint on the wire tip to hide it. Testing was interesting ... he plugged it into a variac (which I controlled) and sat on it in a bathing suit. At about 90v he felt it. What could I do? I gave him an 'A'.
If electrical SAFETY had been a significant part of the course, you'd have had easy justification to give him an 'F'. But maybe I'd have given him a 'D' if it were wired to trip the bathroom GFCI when someone sits on the seat.
