There was an AOL instant messenger exploit back in the day where you would send a link or attachment or something and it would cause the other person's desktop wallpaper to change to a big dick or something, and all of the desktop icons were turned into other porn thumbnails. Lastly, it would turn the windows 95 or 98 or whatever volume up to 100% and blast porn tracks. It was brutal. My friends would do it to each other all the time.
