In Buffy vs Dracula, Buffy says “‘killer’ just sounds so…like I paint clowns or something”, which is a reference to serial killer John Wayne Gacy, Jr., who had a hobby of painting clowns.

Xander says in Buffy vs Dracula, “where’d you get that accent, Sesame Street?”, and he impersonates Count von Count from the children’s show. In Disharmony, the following conversation refers to the character Big Bird, from Sesame Street:
Cordy: “Whoa. Big bird”
Gunn: “Big Bird?”
Cordelia: “Not the muppet, dumbass…”

In Buffy vs Dracula, Willow says, “Just call me the Computer Whisperer”, which is a reference to the book The Horse Whisperer, by Nicholas Evans. A movie of the novel starring Robert Redford, Kristin Scott Thomas and Scarlett Johannsson was made in 1998. Interestingly, Anthony Stewart Head’s partner Sarah Fisher …

Dracula mentions that Buffy’s power is “rooted in darkness” in Buffy vs Dracula. In the season seven episode Get It Done, we discover that the Shadowmen created the First Slayer by using the energy of a demon.

Riley offers Buffy a jelly doughnut whilst at Giles’ house in Buffy vs Dracula. In The Zeppo we discovered that both Buffy and Giles love jelly doughnuts.

Joyce apparently knows nothing about Willow and Tara’s relationship in Buffy vs Dracula as she says, “Oh, when you girls are older you’ll understand. It’s hard to date. Sometimes you just…feel like giving up on men altogether.” She apparently finds out before the next episode as Dawn mentions in her …

When was Dawn created by the monks? There’s a suggestion in Buffy vs Dracula that it was as late as during that episode, as Joyce comments (as she and Buffy eat alone) that the house will get quiet when Buffy goes back to college.

Scott Berman, who played one of Dracula’s movers in Buffy vs Dracula, played ‘Vendor’ in the Angel episode ‘Blind Date‘.

Edward James Gage, who played one of Dracula’s movers in Buffy vs Dracula, played ‘Mordar the Bentback’ in the Angel episode ‘Judgement’

Jennifer Slimko, who played one of the vampire girls who toyed with Giles in Buffy vs Dracula, also played a Romanian woman in the Angel episode ‘Five By Five‘.

The poem Willow is painting on Tara’s back in her dream in Restless is by Sappho and is in the original Greek:

Deathless Aphrodite on your lavish throne,
Enchantress, daughter of Zeus: I beg you, queen,
Do not overpower my soul with heartaches
and hard troubles,
But come here, if ever at another time
Having …

Joyce’s seduction of Xander in Restless is similar to the events of 1967 film The Graduate, starring Dustin Hoffman and Anne Bancroft. Buffy’s line in Into the Woods, “Are you planning to seduce me, Mr. Finn?” is a paraphrase of the famous line from The Graduate, “Are you trying to …

The appearance of the first, original Slayer in Restless raises some interesting points not yet explored in the show. The episode is essentially an epilogue for the forthcoming season, and in the next episode (Buffy vs Dracula), Buffy tells Giles that she wants to find out more about what it …

In Buffy’s dream in Restless she says, “Faith and I just made that bed”. Buffy and Faith actually made the bed together in Faith’s dream sequence in This Year’s Girl. A dream sequence that references someone else’s dream sequence!

Willow’s dress in Restless is obviously supposed to be the one she wore in Welcome to the Hellmouth, but it’s actually slightly different. The season one dress was a small plaid and this one looks as though it’s made of panelled suede.
