So apparantly PHP has easter eggs.

Find a site with PHP, and put this after the .php

?=PHPE9568F35-D428-11d2-A769-00AA001ACF42

Such as
http://www.antionline.com/index.php?...9-00AA001ACF42
It will display the Zend logo.

http://www.antionline.com/index.php?...9-4C7B08C10000
Shows credits (w/ version).

http://www.antionline.com/index.php?...9-00AA001ACF42
Shows a PHP logo.

http://www.antionline.com/index.php?...9-00AA001ACF42
Shows a puppy.

Worst part is that some of these change with the version of PHP (fingerprinting). They can be disabled by altering you php.ini file, (expose_php), but apparantly Antionline didn't know about it.

I don't think I like easter eggs in open source projects. Waste of code IMO.
