In the episode "Apartnership", the one where its Cosmo and Wanda's anniversary and they have a fight, so they go on the fairy dating game. Anyway, at one part when Wanda starts talking during the Game Show, they shoot a plunger onto her mouth to stop her from talking. Later, she starts talking again, and they shoot one of those fuzzy, toilet cleaners into her mouth. (I forget what they're called.) Anyways, it shows Cupid saying they'll be right back to ask the final question, in the background, Wanda has a plunger instead of a fuzzy toilet thing in her mouth.
