Well it looks like ThinkGeek is ready for April Fools Day already by announcing their latest gadget – TV Poltergeist. Piss your friends off by suddenly having the TV go off right when the secrets of the island on Lost are about to be spilled. Just program the TV Poltergeist to turn on and off any TV at random intervals every 5 to 20 minutes. If you are really determined to drive someone insane, you can have it happen 24 hours a day, for weeks at a time. All you need to do is hide the device somewhere near the TV but be sure to aim the LED toward the TV for it to work. The best part? It’s cheap enough device (only $12.99) that you could buy several and prank someone who has multiple TVs, but I would anticipate that you probably won’t be invited back to their house ever again.
