When Furby's first hit the market, it turned out a number of them had been hacked to scare small children, boxed up, then shipped to the States. Most of the defective ones ended up in discount stores. A friend got his daughter one. It uttered all sorts of calming things to sooth the the kiddies at bedtime, such as "Kill your parents" and my personal favorite, "I want your eyeballs".
I was at their house when she was packing up to head to grad school. She was looking for something in her closet and found the "Furby From Hell" in a box at the back of the upper shelf.
They had a heavy duty paper cutter downstairs. She came down, dismembered it with the cutter, carried it out the backdoor, threw it in the fire pit, and lit it up. She came back in and said "That will take care of that f@#*in' thing."
