Maat13 I'm pretty sure Gregor's comment on yard sales was a bit tongue in cheek. At least it made me laugh.
Yard Sales are the source of many JW urban legends where someone would experience strange happenings around their house after buying the odd item from a yard sale. Putting the item in the car usually took care of the the strange happenings until it was convenient to dispose of it properly. Burning it was always a good option. I don't know why you couldn't just say jehovah at it a couple times.
Strangely I know of 3 people who claim to have had these experiences. They included a bird cage, a hobbit book and a set of candlesticks. I know the bird cage was from a yard sale, not sure about the other two. One was a “ friend” of mine that I suspect may have been exaggerating. Another was an ex-hippie who may have been having a flashback. The third was from my Mom with one of her bible studies. I’ll have to ask her about that next time I talk to her. I remember hearing about how they smashed them up and threw them away.
