Kitty movies: Xander says of Giles, "Faster pussycat! Kill! Kill!" - This was one of the all-time classic trashy B-movies made by Russ Meyer in 1965. Rumoured to be based on a greek myth, the plot consisted of three strippers who hit the road in their sports cars and crushed everything in their path, plus a wheelchair-bound old man. Not actually Theseus and the Minotaur then.

Latin isn�t dead: When Willow recites the spell to keep Angel out of the house she says "Hicce verbis consensus rescissus est" - which is Latin for "By these words permission is rescinded". Those of us who weren�t forced to study the dead language at school can translate it as "You can�t come in, mate".

Invited guests: When Cordelia says that she once let Angel into her car, this was most likely in Some Assembly Required. They left the school together after Cordelia found an arm in a skip.

Opera of death: La Boheme by Puccini is playing when Giles returns home. The words in the scene are full-on lovey-dovey stuff, not quite creating the mood for finding your true love dead in your bed.

The head can sing: Anthony Stewart Head provides the vocals to the music for the scene at Jenny�s grave.

Doggy dancing: Willow mentions A Charlie Brown Christmas. This was the first animated Peanuts feature and is shown annually on TV in the US. It also features the first mention of the Snoopy Dance - something we finally see Xander do in season five�s The Replacement. The dance involves throwing your head back, holding your arms stiffly at your sides and bopping away to your heart�s content. Altogether now...

Jew know what?: It�s been hinted at in previous episodes that Willow�s family is Jewish. Now she confirms it. (Like we couldn't have guessed with a surname like Rosenberg?) Her father is called Ira and is apparently very religious.

Slipped disk: Jenny's computer disk falls between two desks at the end of the episode. Don't think that will be the last you see of it.
