Charmin Lee who plays Beverley in this episode also plays Lisa's sister Darcy in a future episode
Lisa is spraying for bugs and says, "I'm coming for you Charlotte. And don't be calling for Wilber. I ate him for lunch!" This is a reference to "Charlotte's Web," a book by E.B. White, about a spider named Charlotte who tries to save a pig named Wilber from the slaughterhouse.
