I remember
some years ago there was a baseball bat made of foam, you
coud use to slam your television if you see something you don't like.
Since it was connected to the power outlet of the TV set, and if I'm not
mistaken to the video input, it flashed the tv and turned it off for
some seconds. Man, it was FUN! :o)
YES! I remember those! Where did they go?
Not that I watch TV
anyway, but that could be useful for other things as well.
