Cultural references

 * 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.

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."
 * Martin Spivak is seen at the wedding sitting with Bitzi Baxter. Buster had imagined his mom dating him in the episode "Bitzi's Break-up" but they have never been seen together in real life until this episode.

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 is suggested that the parlor is renamed in the future.
