I had a Casio remote control watch that I was actually using all the time in my room. I used it in an evil way only once, since the TV sales guy was showing off how loud the super high-end TV is. As he turned the volume up with a maniacal smile, I just pressed OFF button. New money couple lost interest immediately.
It is Casio CMD-40 for the interested.
I refuse to answer such a stupid question.
