Cultural references

 * Mr. Ratburn reads Love Poems by Pablo Neruda.
 * Ms. Turner gives Arthur, Buster, Francine, and Muffy a book called How to Write Poetry. Its color scheme and cover are very similar to the For Dummies series of guides.
 * Patrick Ratburn names his chocolate of the day after Frida Kahlo, the iconic Mexican artist and activist.

Episode connections

 * Muffy is excited about a wedding. She previously "hosted" one in "D.W. Unties the Knot".
 * Buster thinks that teachers don't have lives outside of school. This idea also comes up in "The Rat Who Came to Dinner" and "Lend Me Your Ear".
 * In "Bitzi's Beau," Buster imagines his mother marrying Mr. Ratburn.

Errors

 * The overhead sign at the Sugar Bowl says "Sugar Free Bowl." The aerial view of the building was likely recycled artwork from "D.W. and the Beastly Birthday" when it's suggested that the parlor is renamed in the future.
