I could imagine entire soundboards being created to spoof people into viewing internet shock sites, etc.

For example, lets pick on Leo Laporte, because I like him and he's famous in the tech journalism community. He must have thousands of hours, tens of thousands of hours, of digital audio free for use on the net. So all you need is a simple audio editor and an audio player to play the spliced commandline and you can spoof him. So at any time in his long recorded career has Leo ever said the words "girls" and "one" and "two" and "image" and "cup" and "google" and "search"? Well, I think he could be shock site'd pretty well with this technique. Not just shock sites, but rickrolls would be funny too.

This takes some planning ahead, but not much.
