The Best Prank That Isn't a Prank

I created a fake virus scanner once. It scanned my friend's computer and found "456 viruses including Sadness.exe and Loneliness.doc." He almost cried.

The best part? These fake scanners can find whatever you want. "Congratulations! Your computer is 100% virus-free except for Love.exe which is not a virus but should be deleted anyway."

The Comedy

The humor comes from the complete lack of understanding of how computers actually work. Your computer doesn't have "moods" or "feelings." But it COULD.
