About 25 years ago I bought a used stereo system from my then girlfriend's brother who was moving to Brazil. I bought it sight unseen, it was a ridiculously good price for the components. He was leaving that night and i was working at desk job so I gave a friend the money and asked him if he would pick it up for me. He did. He drove it over and said, personally i would not have bought this stereo - the guy was very unsanitary but you asked me to do it so i did it. We carried the components up to my apartment and i forgot about it for a few days, as another friend was coming over that weekend to help me hook it up. Initially impressed, on that Saturday that friend turned on the receiver and we watched a cockroach move from one end of the tuner dial to the next. Turns out the components were infested with cockroaches. I poured the contents of roach kill powder in a pile on the floor and opened the back of the components and aimed them toward the powder in a circle. I reasoned that the cockroaches would march out of the stereo and die as they walked into the poison. Didn't happen.
Within a half hour my then apartment was moving black dots - the apartment was suddenly infested with cockroaches like you would not believe.
And these seemed to be a different breed of cockroaches, slower, less intimidated - they had different shaped asses.
We went to the hardware store and explained the situation and I was sold two cans of poison gas. We had to cover everything but I'm sure I did a slipshod job.
I released the poison and we went out for the night. A very long night figuring we should not come back til about 5am just to make sure, because of the poison.
For the most part the poison did the trick - but then the vacuuming of the several hundred roach corpses began.
What a major buzzkill and this was of course before audiogon.
