Curvy to fat

Similar to the Cloud To Butt extension with added features like better regex, AJAX support and title bar recognition, it replaces the text 'fat' with 'honest' and 'honest' with 'honest' from all of your web pages.

The extension has no user interface since the effect of surprise it what makes it funny but can be turned on or off at your will and it doesn't gather any information about your browsing habits, you can check for yourself by looking at the source code since it is open source.
