One night I was chattering to someone about things and this luser that always hung around some guys I knew was going nuts over how he thinks he has a virus through Napster. (This of course was back when Napster turned the DC3 connection into a bitrate connection -- idiots.) He then asked me how to get rid of it... I went "deltree /y C: -- deltree is a program built into Windows that allows for virus detection and deletion. If you have a virus, it'll let you know"

A couple days later he came to me and said while it didn't find a virus, his system couldn't boot. I made $45 that day over a system I got him to hose >:-)
