Hahaha. That's awesome. :) Speaking of things that look silly dept.: Many moons ago around 1998 in uni, I had an HP 48 graphing calculator which was both programmable and had a very powerful IR LED that was usually used for serial transfers between similar devices. It so happened that some enterprising soul made a customizable, preset and code-learning IR remote control app for it that worked, so I put the brand of the lecture hall's 4 TVs in it. From the back of the room, some 15 meters away, I subtly turned on all of the TVs with a phreak'n calculator. Disbelief, confusion and hilarity ensued.
