Ages ago, when I was in Junior High, I was helping a friend of mine upgrade MS-DOS to version 4-something on his parents' IBM XT.
To this day, I'm not totally certain where things went sour, but I ended up corrupting the computer's FAT tables in a nasty way. Upon doing a directory listing, and getting back nothing but a screen full of garbage ASCII, my friend started to sweat profusely.
As it turns out, his dad was doing his company's payroll on that machine. That was a bad night.
Oh, and not two weeks later, I did it AGAIN, fux0ring the family computer of another friend of mine.
Frankly, I'm amazed that I have any friends left.
