- In "The Spring Chicken is Coming!", Oona's lunch consists of a SUSHI roll.

- And in the Cold Open of "The Grumpfish Special!", Gil lifts up the platter to reveal one of the Little Fish.

- "Ducks in a Row!": Besides the obvious parade pun, the idiom "get one's ducks in a row" means to organize things well, which is exactly what Nonny does at the end.
