Goof: At the end of the episode Buffy says she saved up for new shoes, but will have to use the money to have the tattoo removed, and she hopes her Mom won't see it before then. Yet when she is talking to Giles a few minutes later, we have a clear view of her back where the tattoo was, and it has disappeared.
Goof: In the library scene with Buffy doing her aerobics the shots from behind Giles show him with his hands over his ears and both elbows on the table. When the shot changes to Giles from the front he now is sitting upright with both elbows in the air. The angle again changes to behind Giles and his elbows are back on the table.
Goof: When Philip escapes from the library cage, Buffy starts to move to kick him. It appears to be her left leg about to hit his right side, but when it suddenly changes to another angle, it's her right leg hitting his left side.
Nitpick: When Deirdre (the possessed woman at the beginning of the episode) falls to the ground just before she dissolves, her neck, face, and hands are decayed-looking. But her legs don't match up with this as they appear to be healthy looking flesh.
Goof: In the scene when Demon-Jenny pushes Buffy against a dresser with the table and Giles walks in, they show Buffy falling to the floor. But when Giles tells Buffy to leave, they show her standing up against the dresser as if she never fell.
Buffy: Xander, how do you feel about digging through some of Giles' personal files and seeing what you can find?
Xander: I feel pretty good about it. Does that make me a sociopath?
Xander: Yep, yep, I knew this would happen. Nobody can be wound as straight and narrow as Giles without a dark side erupting. My Uncle Rory was the stodgiest taxidermist you've ever met by day. By night, it was booze, whores, and fur flying. Were there whores?
Buffy: He was alone.
Xander: Give it time.
Xander: Y'know, computers are on the way out. I think paper's gonna make a big comeback.
Willow: And the abacus.
Buffy: All's well that ends with cute ER doctors, I always say.
Giles: Just don't be late.
Buffy: Have I ever let you down?
Giles: Do you want me to answer that, or shall I just glare?
Cordelia: I've got the solution right here. "To kill a demon, cut off its head."
Xander: Oh, yeah, we'll find Ms. Calendar, then we'll decapitate her. Hey, she'll be the first headless computer teacher in school. You think anybody'll notice?
Cordelia: Do you know what you need, Xander, besides a year's supply of acne cream? A brain.
Jenny: All right, guys, the first thing we're going to do is... Buffy.
Xander: Huh? Did I fall asleep already?
Willow: Aw, you miss your friends?
Xander: Sit here, Buffs. De-militarize the zone between me and Cordelia.
Cordelia: Yeah, and de-louse him while you're at it.
Cordelia: Well, evil just compounds evil, doesn't it? First, I'm sentenced to a computer tutorial on Saturday. Now I have to read some computer book. There are books on computers? Isn't the point of computers to replace books?
Giles: Cordelia, I'm a little busy right now.
Cordelia: Oh! Great! Can you help me with a ticket? It's totally bogus. It was a one-way street. I was going one way.
Cordelia: What?! Why does everyone always yell my name? I'm not deaf! And I can take a hint...what's the hint?
Angel: Maybe he's late.
Buffy: Giles? Who counts tardiness as, like, the eighth deadly sin?
Willow: Do you think Giles ever played "Anywhere But Here" when he was in school?
Xander: Giles lived for school, he's actually still bitter that there are only twelve grades.
Buffy: He probably sat in math class thinking, "There should be more math. This could be mathier."
Willow: Come on, you don't think he ever got restless as a kid?
Buffy: Are you kidding? His diapers were tweed.
Buffy: And you know what? I have just the perfect music. Go on, say it. You know you want to.
Giles: It's not music, it's just, uh, meaningless sounds.
Buffy: There. Feel better?
Giles: Yes. Thanks.
Jenny: Mm, no, I'm fine. I mean, I'm not... running around, wind in my hair, 'the hills are alive with the sound of music' fine, but... I'm coping.
Cordelia: This is what happens when you have school on Saturday.
Cordelia: I'm gonna be in therapy till I'm thirty.
Xander: Dead guy here interrupted our tutorial. (To Philip) Been meaning to thank you for that.
Buffy: I'm not going to lie. It was scary. I'm used to you being, you know, the grown-up. And then I find out that you're a person.
Giles: Most grown-ups are.
Buffy: I know you! You ran that costume shop.
Ethan: Oh, I'm pleased you remember.
Buffy: You sold me that dress for Halloween, and nearly got us all killed!
Ethan: But you looked great.
Giles: Must we have this noise during your calisthenics!?
Buffy: It's not noise! It's music!
Giles: I know music. Music has notes. This is noise.
Buffy: I'm aerobicizing! I must have a beat!
Giles: Wonderful. You work on your muscle tone while my brain dribbles out of my ears.
Xander: Oh, gang, didja hear that? A bonus day of class plus Cordelia! Mix in a little rectal surgery and it's my best day ever!
Giles: The rest is silence.
This line that Giles is quoting comes from Shakespeare's Hamlet. After Hamlet has killed the king and gotten revenge for his father's death, he lies dying from poison, and he tells his friend Horatio to tell everybody what really happened. Then he dies, and his last words are "the rest is silence." (Hamlet, V.ii.357)
Giles: Aah. Very good. And the rest is silence.
This is part of the same quote used in the original movie by Buffy's first watcher, Merrick, just before he died. "When the music stops, the rest is silence." A vamp was fried on the circuit board and the music from the gym was cut out. Buffy was broken out of the vampire boss, Lothos's, trance and was able to continue fighting on.
Giles: Bay City Rollers, that's music.
The Bay City Rollers are a pop band that was popular in the 70's. Their biggest U.S. hit was the 1975 release "Saturday Night".
Ms Calendar: I mean, I'm not running around, wind in my hair, the hills are alive with the sound of music fine, but...
Ms Calendar refers to the famous scene from the movie The Sound of Music, where the character played by Julie Andrews, runs across a field, her hair blowing and singing with joy.
Buffy: ...You Lost Weekending in your apartment.
The 1945 movie The Lost Weekend is about an alcoholic who ends a period of sobriety with a weekend of binge drinking. Buffy is referring to the fact that the normally quite sober Giles had apparently been drinking heavily in his apartment.
Xander: De-militarize the zone between me and Cordelia.
After a war, an area can be set aside as a buffer between the formerly warring parties. The best known de-militarized zone is between North and South Korea.
Buffy: Giles, who counts tardiness as like the eighth deadly sin.
A reference to the seven deadly sins: pride, idleness, gluttony, lechery, avarice, envy, wrath.
Cordelia: Yeah, when you've visited decaf land.
Cordelia references the fact that caffeine in coffee can make people jumpy and irritable. This is likely a subtle inside joke, since the actor that plays Giles, Anthony Steward Head, is also well known for appearing in a series of Taster's Choice coffee commercials.
Buffy: All's well that ends with cute ER doctors, I always say.
This is possibly just a generic reference to emergency room doctors, but certainly calls to mind the television show ER. The show was the most popular drama in the United States and its doctors (namely George Clooney) were highly regarded for their cuteness.
Buffy: I'll bring the party mix.
Party mix is any of several combinations of Chex cereal, pretzels, peanuts and seasonings.
Buffy: Mmm. Vampire Meals-On-Wheels.
Meals-on-Wheels is a organization that arranges to deliver food to the elderly in their homes. The idea is to assist those who have limited mobility while still enabling them to live independently.
Xander: Amy Yip at the waterslide park.
Amy Yip is an actress from Hong Kong. She's most famous for her well endowed figure. Xander no doubt picked the waterslide park location so that she'd be wearing a bathing suit.
