In "The Potty Problem", Big Mouth has to go to the bathroom (presumably Number One, since he'd just done Number Two recently), he didn't go until Peg and Cat sung a song, and then the second time, he did it while everyone was out of the bathroom. People with shy bladders sometimes use music to distract themselves.
The Neighbor Ladies are a couple.
I mean, the two even have a photo of them together in their house. Though, if they were a couple, they might like stereotypes a bit less, as couples of the same gender are often stereotyped.
- "Their house"? They don't live together.
Roxanne is Ramone's cat.
I mean, Peg is awed by Ramone because of his talents, and the same is true for Cat and Roxanne. Though admittedly, it's implied that Cat also has a crush on Roxanne
, whereas Peg is just impressed by Ramone's talents like 90% of the cast is. Their names even both start with "R" and end with "N-E".
