I was in college at UCSD when the 14-Mb shareware DOOM was released. I finally found it (after frantic searching) on a public FTP server somewhere in Australia. I started the download, then went to dinner. After eating, I came back to both the completed file and a salty email from the Aussie sysadmin admonishing me for saturating their connection. The next few days (and my GPA for that quarter) were a bit of a blur. Good times. :D
