Being in a shared office, I quickly pissed that screen off and shut down the Internet, then turned around to greet my boss (female) who had just walked into the room.
After providing her with a five minute update on my day's activities, I turned around and was aghast to see the 'Knocked up Black Chicks' web page large as life on my screen. It took me about five minutes before I was able to escape the hundreds of porn applets that had invaded my system.
Next day at work a 'Gold Edition' Hustler Magazine arrived in the mail addressed to me and was promptly opened by the boss. She retrieved the 'please explain' email from her drafts and got back to work.
PS - the mag contained a story about an erotica exhibition at Metro 5 Gallery who I did PR work for, so I survived again...
