- "Funny Aneurysm" Moment: The Trope Namer — Buffy is commenting on how her mother would react to the price of her text-books, stating flippantly, "I hope it's a funny aneurysm."
- Hilarious in Hindsight: In the midst of Xander's Reference Overdosed Dare to Be Badass speech are the words "Avengers, Assemble!!" Joss Whedon would end up directing the first two Avengers films in the Marvel Cinematic Universe.
- Magnificent Bitch: Sunday is a pragmatic vampire who chooses UC Sunnydale as her haunting ground. Targeting the college's freshmen, Sunday's group sires the students and then steals their things from their room, leaving behind a note saying that the student simply couldn't handle the stress and dropped out to deflect suspicion from her. As Buffy learns, Sunday has been doing this for over a decade, deliberately taking enough students to establish a pattern without taking so many that police get suspicious, explaining why she has never been caught. Managing to survive a head-on confrontation with Buffy, Sunday then pulls her routine on the Slayer herself, demoralizing her to the point that she almost gives up completely. When Buffy recovers and finds her hideout, Sunday comes close to defeating her once more, showing strength and skill unmatched by other vampires.
- Retroactive Recognition: Eddie is played by Pedro Pascal (through credited as Pedro Balmaceda), whom you might recognize as Oberyn Martell a.k.a "The Red Viper" (among others).
- They Wasted a Perfectly Good Character: Joss Whedon regretted killing off Sunday, as he felt that she had potential (she was originally supposed to be a former slayer-turned-vampire).
