Horror movies: The tapes in Tucker�s video collection, (which he uses to taunt and train the devil dogs), are:

• Prom Night (1980) - a slasher movie starring Halloween's Jamie Leigh Curtis about a hooded killer who�s avenging the death of a bullied young girl.
• Prom Night IV - Deliver Us From Evil (1992) - pseudo-sequel to Prom Night, about a homicidal priest who goes on the rampage after waking from a thirty-year coma! (Presumably Prom Night II - Hello Mary Lou and Prom Night III - The Last Kiss were out when Tucker visited Big Lou�s video store!)
• Pump Up The Volume (1990) - campus drama about a high school student (played by Christian Slater) who hosts an incendiary pirate radio show. The film featured Seth Green (Oz) and Juliet Landau (Drusilla).
• Pretty In Pink (1986) - John Hughes movie about the adolescent struggles of a misfit teenage girl (Molly Ringwald).
• Carrie (1976) - influential movie about a young woman (Sissy Spacek) whose powerful telekinetic powers are unleashed at the school prom. The film is also a name-checked in Buffy�s line "Gotta stop a crazy from pulling a Carrie at the prom". The film is based on Stephen King�s first novel, published in 1974.

Musical mayhem: Several songs are referred to, either directly (Sister Sledge�s 1979 hit We Are Family), or indirectly (Prince�s 1999 (1982), in Buffy�s line "Now I'm gonna lock you in here, and then I'm gonna party like it's ...[1999]"). The song that lures the devil dogs back towards the prom is Kool and the Gang�s biggest hit, 1980�s Celebration. The song that Angel and Buffy dance to at the end of the episode is The Sundays� Wild Horses (a late addition to their 1992 album Blind, Wild Horses is a cover version of a track on the 1971 Rolling Stones album Sticky Fingers).

Timeless Angel: Buffy�s assertion that Angel is 243 years old again contradicts the continuity mentioned in Becoming - Part One, (which states that Angel became a vampire in 1753). In Earshot, Some Assembly Required and Reptile Boy, Angel�s date of birth is given as 1755 or 1756.

Dressing up games: Cordelia�s presence at the April Fools dress shop (in Choices) is clarified, setting up Xander�s touching act of kindness later in the episode.

Bloodthirsty: Joyce�s line to Angel "You don't drink? Beverages, I mean?" may be a nod to a famous quote from Universal�s 1931 film version of Dracula, starring Bela Lugosi. In a scene where the Count is entertaining his lawyer, Renfield, he says "I never drink� wine"!
