When I was a teenager and my brothers started bothering me with their loud
TV, I took a 220V relay, put one of the coil leads through its normally
closed contact group, and plugged the relay into the mains behind the wall
where the TV was. Made an exelent TVI/RFI generator, I thought the TV is
going to blow up.

Back when I was living in a college dorm, the guy in the next room had
pretensions of being a musician - specifically, a drummer. His way of
"practicing" was to turn up his stereo - really loud - so he could
feel the bass, then put on headphones (so that the highs wouldn't hurt
his ears) and then drum along with the music.

Needless to say, this did not make him popular with me or my roommate,
the people on the other side of his room, or the folks downstairs (or,
I suspect, people in the next county). Numerous complaints were filed;
he kept on drumming.

The guy on the other side realized that the drummer's stereo was
plugged into an outlet on one side of their shared wall, and that he
had an outlet on the same circuit. The next time the booming started
up, he plugged his old fluorescent desk light into the outlet, and
then started vibrating his thumb on the pushbutton make/break "start"
switch.

BRRZZBuzzzBZAP.

Stereo goes off suddenly. Two minutes of blessed silence. Stereo
goes back on and the drumming starts again.

BURZZRfffBUZZT.

Lather, rinse, repeat. Eventually, the drummer gives up for the day.

I understand that the drummer never did figure out what was wrong with
the stereo, despite two trips to the repair depot. He left the dorm
at the end of the quarter (I suspect he was "asked" to depart by the
Powers That Be) and we could sleep and study in peace once again.
