Barry Cuda is a parody of the singing fish animatronic Big Mouth Billy Bass.
First appearance of Alexander and Terry, though Alexander's name is not spoken until "Spaghetti Theory" in Season 2.
The only accusation Cricket was technically correct about was Gramma's, as when the family was destroying Barry together, Gramma can be seen hitting him with a frying pan like the one she used to burn Barry in the fantasy.
Moral for Barry Cuda: Cricket learned not to bother his family with something that he likes but they don't to the point of annoying them. He also learned nothing can put a price on his family.
