I had a very nerdy roommate in college (I'm nerdy too, so it's ok) who had a Lamp Commander set up in his room. Basically, it's a voice activated power strip/outlet that works like the clapper. Say; "Lamp Commander" BEEP beep, "Lights on." boop. "Lamp Commander," BEEP beep, "Lights off." Boop.
Anyway, my roommate (call him B) always had a very messy room, and his habit every night was to go into his room, climb onto the top bunk, turn on his lights and read for a while. One night when he was out, we took the bottom part of a blender, plugged it into the lamp commander, and buried it under some clothes. Some time after midnight, B comes home and sleepily goes to his room. A few minutes later, I hear him jump up onto his bed and say "Lamp Commander." Suddenly the electric motor of the blender kicks on, scaring the crap out of him. He can't figure out what's going on, and since the blender makes so much noise, the voice recognition won't let him turn it off. He climbs down and frantically searches through a 3 foot pile of clothes and books looking the whatever the machine is.
B came out of the room, looked at me, and I just pointed to the other room where my other roommate was sleeping. B marched in, plugged the blender into the wall, put it on high and walked out. My other roommate, who helped set it up woke up confused but then started laughing. B was pretty pissed.
