I read a complaint by a guy who complained that his next door neighbor
who is a ham is constantly interfering with his car's AM radio.

The reason he knows this is because the interference on his car radio
increases every time he starts the car's engine (which is the ham's
fault) and then increases even more every time he presses the gas
pedal. (which is also the ham's fault).

The guy is obviously causing his own interference to his car radio
every time he starts his car and then even more whenever he presses
the acceleratorr, not the ham.

But of course, he blames it on the ham next door.
