Computers. I bought my house mate's old one some years ago, and put a lot of money in to fixing it up. Moved down to Florida for a job, With my compuyer, "good as new". My new room-mate, a coworker, bought us a new game to try. Loaded the game and error msg. Nothing worked.
I felt that the computer was pure evil, having sucked up the last of my money and refusing to work.
I had a survival knife I was using as a rigging knife (overkill, but fun). The blade was just a tad thicker than a 3.5" floppy disk. It inserted silently into the disk drive, but for a faint "shhhhhlllkkk". I used the knife blade as a lever and did some damege. I then removed the case and hacked at the main CPU chip with the knife.
Surprisingly, the silcon combo is very, very tough, and it was difficult to scratch the chip. I took some gouges out, not really chips in the chip.
I then took the carcass outside to the dumpster and threw it in. It felt good. Real good.
