Sundry software stuff
Too many to remember. Here are some decent ones.

We hex-edited the Microsoft BASIC interpreter (DOS 3.3 days) to read "Bad Ass BASIC". Changed the 'OK!' prompt to "YO!", and changed 'subscript out of range' to "SUBSCRIPT TOO DAMN BIG".

We added a menu to the boot process (AUTOEXEC.BAT) asking whether you were a good student or a bad student. If you answered 'Good', it dumped you to a DOS prompt. If you answered 'Bad', it printed a page of ASCII art pron on the dot matrix printer and started SpaceQuest.

My manager somehow got a screen-flipper program (turns the screen 180°) added to his startup group.

A mate used to complain about how he never read the "Risk Management" daily recap e-mails, so I set an Outlook rule to forward mine to him.

You'd be surprised how many people aren't all that interested in messenger messages from the command: "for %v in (C:\Windows\System32\*.*) do net send //computername %v"
it sends a messenger message for each file in the system32 directory, which can easily be several hundred, just stating the name of the file.

I once reset a user's password to "twentyfivecharacterstring" (which happens to be one) and checked 'user cannot change password'.
