The Geek Shall Inherit the Earth. A small shrine to the nerdiest supervillans on TV. This week: Warren refers to 'parsecs' - units of astronomical length equal to 3.258 light years. Andrew wears a t-shirt depicting Big Mel, mascot of Doug Petrie�s favourite favourite comic book store, Meltdown in Los Angeles. "Are you a Jedi?" asks Andrew of Warren, wondering if he has the powers of Star Wars's mystical knights. The geeks do Star Trek Vulcan salutes, and Warren quotes Captain Picard's catchphrase, "make it so". We see the Troika playing a game which appears to be Dungeons and Dragons. The geeks' list of objectives reads: Control The Weather Miniaturize Fort Knox Conjure Fake I.D.s Shrink Ray Girls Girls The Gorilla Thing Hypnotize Buffy

Pipe bonding: Buffy's "So, we meet at last, Mr. Drippy" to the leaky tap in the basement is a reference to words often uttered by the villain in Bond movies.

Bedraggled Buffsters: According to Flooded's Co-Writer and Director Doug Petrie, a special waterproof floor was built for the flooded basement set. Sarah Michelle Gellar and Michelle Trachtenberg gamely allowed themselves to be soaked during filming, and Doug even bought the latter a special towel with her name on it for braving the icy water.

Little Bird: This episode is brought to you by the numbers 2 and 55 - as seen printed on Dawns tops. No, they're still not any kind of secret code. Dawn's "Mmmmm, cookies" explanation of how M'Fashnik is pronounced is more Homer Simpson than Cookie Monster though.

Burning beauty: Buffy jokes about burning her house to collect on the insurance because, "Fire pretty." In the season three finale, Graduation Day Part II, she notes: "My brain isn't really functioning on the higher levels. It's pretty much: fire bad; tree pretty."

Charges whatever a spider can: Xander once again proves his Spider-Man knowledge knows no bounds by confirming that the webbed wonder doesn�t work for cash. "Action is his reward," he says. Anyway, doesn't everyone know that Spiderman gets his money from alter-ego Peter Parker's job as a press photographer?

Coincidentally, Jeph Loeb, Executive Producer of the abandoned Buffy: Animated series, has written several Spider-Man comics, including the recent Spider-Man Blue.

Fashion victim: Never slay in a long skirt. It might help you get taken more seriously when applying for a loan, but it really cramps a Slayer�s style when trying for those killer kicks.

Pleased to geek you: We've met all the geeks before, except Andrew - but we have met his brother, Tucker, who sent hell hounds to the Sunnydale High Prom in season three's The Prom. Annoyed at the two of them being mixed up, Andrew points out that he played the much cooler trick of sending flying demon monkeys to the school play.

Country seat: Giles claims he keeps a flat in Bath - rather an expensive thing to maintain during all the time he's been in the US, surely? The location is a jokey nod to the fact that Tony Head actually does live in the Bath area. But we're not telling you where exactly.

Real horrorshow: Describing just how scary doing the resurrection spell had been, Willow says "the Blair Witch would have been watching like this," holding her fingers over her eyes. It's reference to 1999's surprise horror hit, The Blair Witch Project, in which a group of young filmmakers are terrorised in the woods.

Heard but never seen: At the end of the episode, Buffy receives a call from Angel. He�d been contacted off-screen by Willow in the Carpe Noctem episode of his own show. Although network wars between UPN and The WB prevented an actual crossover, Jane Espenson speculated as to what might have happened in her Reunion comic.
