This is a simple plugin that displays a wacky quote from George W. Bush.
Place the bushism.php file into your plugins directory: http://www.yourdomain/yourblog/wp-content/plugins/bushism.php
Go to WP-Admin, to your Plugins page, and activate Bushisms.
In your next blog post, put in [bushism], anywhere you like, and the tag will be replaced by a fresh bushism quote whenever the page is loaded (or reloaded).
NOTE: Please do not modify the script. I'm not making any money off of this site. In fact I'm paying to keep it up. If you enjoy the free plugin, please keep the link to my site. Thanks!
