Just something I made up one day over AIM... A sort of modern story of The Boy Who Cried Wolf, yes?

There once was a computer who got lots of pop-ups whenever it went to a site, and many of them read, "Danger! Danger! You have a bug!" The computer user then always said, "No, that cannot be. You're just an ad." So the user closed all the pop-ups and went along with what it was doing. One day, a screen popped up and said, "Warning! You have a virus!" "Yeah, right," said the user and just clicked okay, but alas, that one was real. The computer was ruined, the hard drive corrupted, and all the user could do was yell, "My computer cried 'Virus!' so many times, I never believed it when it was true."
