You want to go to a bar but don't like the World Championship on TV? Just get yourself a TV B Gone

Your TV-B-Gone® universal remote control resembles other TV remote controls, but is different in two important ways. First, 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.
