Voyeuristic intention

Here's a fun google trick:
Type this into google:
-inurl(html|htm|php) intitle:"index of" +"last modified" +"parent directory" +description +size +"Funny pictures"

Of course, you can type in anything else instead of "funny pictures" like "secret recipes" or "reasons to live"

Whatever, what you get is un-indexed directories on the web. Most of this stuff is people's personal stuff they saved on a web page at work or school. Some is stuff that really ought to be protected, some is just dumb, see above.
