Citing sources is crucial to Muppet Wiki. As this database has developed, we've found it ever needful to be sure of our information, and the best way to do that is to clearly identify the sources quotes, background information, and other items which are not located within a production's credits or dialogue. As the many Muppet prove, what's accepted as "common knowledge" is not always fact. Citing specific episodes, books, and newspaper articles supplies a system of checks and balances, and allows for a better Wiki.
