From Lifehacker, we have this gadget. It's called TV B Gone from Cornfield Electronics.
Says the blurb: it only has a power button that allows you to switch a TV on or off. You control when you see, rather than what you see. Second, the device is so small that it easily fits in your pocket, so that you have it handy whenever you need it wherever you go: airports, bars, restaurants, laundromats, etc.
Heh-heh! I'm making a list of places where I want to use this. Besides my own living room, that is.
I should make a new category called "kill your tv."
