This is the first time Timmy's parents and Chloe's parents appear in the same episode.
This is also the first time they interact on-screen.
This is the only episode where Chloe's full name remains the same one used in Booby Trapped, "Chloe Mother Teresa Neil Armstrong Carmichael". In future episodes, it changes from episode to episode.
It is revealed Chloe is a vegetarian in this episode.
However in a previous episode "A Sash and a Rash", after wishing herself in a slacker, she is shown eating bacon. Based off of her parent's reaction to seeing her (Timmy in her body) eat meat in this episode, that could indicate she's only is a vegetarian to please her parents, hence why she was okay with eating it when she's not stressing out.
