Want to get serious about energy savings and force everyone to finally turn off the lights? Then install this cool new Useless Light Switch from ThinkGeek behind your existing standard light switch plate. When you flip the switch of this super convenient, energy saving light switch, a tiny lever pops out from the top screw hole and pushes the switch back to the off position. That's all it does. No matter how many times you try to turn the lights on, they will be instantly turned back off. Problem solved. You'll never leave the lights on again. Ever. However, if you want to keep the lights on indefinitely, just install it upside down. ;)
