A little evil...someone I know wrote into the main internal company web app, a daily check to see if he has logged into the system in the past 10 days. If there's no record of him logged in, it disables the app for everyone in the company.
He wrote the piece once he heard rumors of layoffs, and if he was going down, the company would have to suffer.
The only reason I knew about it, is that he took a 2 week vacation & I called him when the site crapped out. He told me to log on with his username/password...and all was fine again.
Of course..months later we all got laid off.
