Trivia

• This episode reveals that Timmy Turner costed Officer Shallowgrave his job in the episode "Go Young, West Man!".
• Remy Buxaplenty and Timmy Turner's truce from "The Big Bash" is broken by Remy in this episode.
• The acronym 'F.U.N.' is used in a SpongeBob SquarePants episode.
• This was the last appearance, thus far, of Remy. This fact, plus his behaviour (trying to destroy Cosmo and Wanda ) during this episode led many to believe that Juandissimo was taken from him. However, the episode Teacher's Pet reveals that Remy still has Juandissimo as his fairy godparent.
• In one scene Juandissimo poofs up a meal for Wanda, which Cosmo eats and obviously enjoys. That means that Juandissimo's culinary skills have improved as in Remy Rides Again it was stated that he's a horrible cook.
• A goof in this eposide is that the missle would kill Cosmo and Wanda. But they can't die if they are immortal.
• The title of the epsiode is reference to how each epsiode of The Cartoon Network show kdn or kids next door as shown in the title operation fun is just like how a episode of that series would be named after operation.
• Goof: When Timmy, Chester and A.J. run inside the F.U.N. Academy, the A turns pink for a few seconds.
• Goof: When the F.U.N. Academy shows what F.U.N. means, it says, "For Unruly N'er-Do-Wells!". Then when it shows it again, it says, "For Unruly Ne'er Do Wells".
• The irony here is that there is no fun in the F.U.N. Academy.
• Goof: In this episode, Juandissimo's belt is white, not purple.
