I made some good money as a young guy doing NetWare server builds and network troubleshooting.
I accidentally stumbled upon a fun 'bug' in the NetWare networking software for DOS/Windows. If you mixed versions of the software on a Windows machine almost everything would run fine, but if you sent a network message to that machine it would reboot. I shared this information with a few select co-conspirators in the office.
A few choice machines on the company network were so configured and when the douchebag manager rode your ass, you'd just wait until you knew he was neck deep creating some document and then send him a message. The roar as he saw his machine POST and he realized he hadn't hit "save" lately made everything OK.

Few people realize the beauty of white hat hacking.
