The CEO of the company I used to work for as the Network Administrator poured a cup of coffee into his PC because he got a virus from a porn website that he accidentally entered. It posted hundreds of very graphic porn pictures on his screen and he could not get out of it and he did not want anyone to see it. It turned out he only shorted the power supply so when I replaced it the PORN was out of the bag and plastered all over his screen. People do strange things when their PCs misbehave.
