Sean Hickey came up with a way to make a fake page in WordPress.  The obvious question is:  Why would anyone want a fake page?  Sean's answer is that it's sometimes better to execute PHP on a page outside of WordPress rather than creating a WordPress page and using Exec-PHP.  In addition to that, I would add that it's a solution to the biggest problem/feature in WordPress since 2.0 came out:  Restricted page slugs.  Normally, a page slug can't be the same as the category base or any of a series of other special words like "search" and "comments".  With this plugin, you can do exactly that without screwing up anything else.  It's a small thing, but I think it's useful.
