Back when the original first batch of Furbies came out, my sister got one as a gift. It did and said things Furbies do naturally without incident. Until I got a hold of it. I had the brilliant idea of placing it in front of a mirror so it would see its reflection and talk to itself. But I also had a laser pointer and flashed its sensor a few times as it watched itself.
I must have tripped a sensor because I gave the fucking thing MULTIPLE PERSONALITIES.
It started talking to itself in 2 fucking voices, a higher feminine one and a neutral male one. It would say something to itself and then immediately respond. It continued this until we took it away from the mirror but resumed when placed back in front of it. We left it do that until its batteries dwindled down and died. The last guttural chirps out of that thing still haunt me.
