Frat boys: The American College Fraternity system is something like a cross between the Freemasons, a university halls residents' association and a drinking club. With parties.

The first fraternities go back to the eighteenth century, but they really spread in the nineteenth, and now there are dozens. They have names made up of greek letters, like Alpha Kappa and Delta Chi, joining rituals, and usually their own campus properties where members can stay and party. Fraternities and sororities, the female version, tend to be rather upper class.

Recognise me?: Inside the snake costume is Robin Atkin-Downes, more normally seen as Byron, a telepath with a penchant for poetry on Babylon 5. He's also cropped up as an uncredited demon on Angel a couple of times.

Buffi filmi time: Willow and Xander watch a Hindi movie together, but the intricacies of the plot escape them. Hence Willow's attempt to explain. "She's sad because her lover gave her twelve gold coins, but then the wizard cut open the bag of salt, and now the dancing minions have no place to put their big maple... fish thing."

It's not really surprising as a typical Hindi movie story goes something like: girl fancies boy. Boy fancies girl, but girl's father hates boy. Girl rejects father's suggested suitor and sneaks away with boy - both sing and dance. Meanwhile, father's dubious business interests send two goons round to rough him up. Girl's mother dies of shock at sight of husband. Girl returns home and discovers what's going on, resolves to do what father says. Goons kidnap her. Boy tries to rescue her, father makes deal with dubious business interests. Two hours more of singing, dancing, plot twists, finally girl gets boy. The end.

An expanding town: Sunnydale just keeps on growing. This week we find out about Kent Preparatory School and Crestwood College. For a small place, it's a packed one.

The best a man can get: Willow makes a good point on noticing Angel's lack of reflection. How does he shave?

Betel-mania: "I'll bring the betel nuts," says Xander as he invites everyone round for another night of Hindi film fun. A popular "digestive" in India and Pakistan, chopped betel nuts are rolled in lime leaves and chewed. They're mildly addictive, very bitter and turn your spit, and mouth, bright red.

DC Universe: Cordelia contemptuously dismisses Xander's chances of ever belonging to a fraternity of rich and powerful men as likely only "In the Bizarro world." A reference to Superman comics, the Bizarro world is a malevolent, back-to-front version of the real world.
