Here’s a nice little easter egg in Firefox 3. Type about:robots into the navigation bar and see what you get. I love stuff like that, there are some similar things in Google. For example, type “What’s the answer to life the universe and everything?” in, or “number of horns on a unicorn” and Google calculator will provide answers. You can also do this in Klingon or Elemer Fudd by changing the language in “preferences”.
Oh yeah, almost forgot: http://www.youtube.com/watch?v=sIaxSxEqKtA
