A bug in Google?
Here’s a random trick that gave me a few, er, seconds of amusement.
Click in your browser-of-choice’s search bar (I assume you use a browser sensible enough to have such a thing) and type a skeptical/ambivalent smiley, :-/
Somehow I doubt that’s supposed to happen …
(At least MSN and Yahoo! are kind enough to show a “no results found” message!)
