The Mermaid Man and Barnacle Boy Fan Club is a club featured in two of the Mermaid Man and Barnacle Boy episodes. Fish who appear in the club are the background characters that can be seen in Bikini Bottom in other episodes. Most of them are nerdy looking fish that are huge fans of Mermaid Man and Barnacle Boy. SpongeBob and Patrick were kicked out in one episode for questioning these actors in the Mermaid Man and Barnacle Boy movie. But this isn't the only appearance of the MM and BB fan club in the SpongeBob series. SpongeBob and Patrick might have been let back in the club, because in Shuffleboarding, they show their MM & BB fan club membership cards. However, they may have just kept their cards instead of getting them taken away by the rest of the club.
