Not too crazy. More stupid than crazy.
One of the programmers on my team was sitting at his desk looking at porn. And this is cubicle land. No offices. My Director walked into the area to talk to me and saw it. Then it was the first thing he told me about, so I got up and walked over for a look myself and there it was. Me and the Director looked at each and I said I gotta take care of this.
So we walked back to HR, I told them what was going on and what we saw and they told me to fire him. So I did. He lost a $110K job for looking at porn on his computer at work.
