Rocking good horror: This is an episode stuffed full of pop culture references, many of which will mean very little to British audiences. Buffy�s exclamation "Let's do the time warp again!" when they enter the Bronze to find it full of aging adolescents refers to a line from the most infectious song in Richard O'Brien's horror-themed musical The Rocky Horror Show. Anthony Stewart Head played the lead character, Doctor Frank N. Furter in a West End production of the show, so perhaps it wasn't entirely coincidental.
Unwanted Christmas guests: Xander�s question to the uncharacteristically cheery Snyder, "You weren't visited by the Ghost of Christmas Past by any chance?" is, of course, a reference to Charles Dickens� 1843 novel A Christmas Carol, in which the misanthropic Scrooge is reformed by four visiting spirits.
