Duda, the Nobles and the King Agreed

In a season nine episode of the senensence called realty bites, marge is attempting to pass certification tests to become a realter. Lisa helpfully suggests that marge use a pneumonic device to help her remember the details. She then sings an example she made up when she had to learn about magna carda in school. The song represents basically everything i know about magna carta, except that it's no longer actually in force and that british races love to cide it for some reason.
