My very first "virus" was a batch file called win.bat that just scrolled profanity. It was called win.bat because that would make it execute before Windows loaded on a 95 system. It brought the whole computer lab down after I manually "installed" it on each of the 5 machines one day. This was in middle school, and yeah, my middle school was a joke. They ended up formatting all of the machines and the lab was down for half of the semester.
