Xander has a Tweety Pie wristwatch, seen in Never Kill a Boy on the First Date.

In the scene when Buffy and Giles are checking in the morgue lockers for vampires, the items in the background change (light, scale, vent, etc.) but the angle of the wall in the background doesn’t. They obviously kept the camera in the same place for each shot.

The non-U.S. credits for The Witch named Nerf Herder as Nerfherder.

The episode The Witch is also known simply as ‘Witch’.

Willow says to Buffy at the end of The Harvest, “Maybe you could blow something up. They’re really strict about that.” Buffy blew up the school in Graduation Day (Part 2).

Adam pulls the head off the vampire, but when we see the vamp’s body falling to the ground, the head is still attached.

Below is a deleted scene from The Harsh Light of Day:
Willow: “You know what else I love about college? How when the professor comes in, the class gets all quiet.”
Buffy: “Oh, I hate that. I’m always like, what? Did something scary come in? Do I have to kill it?”

Buffy: “But if God keeps telling me to kill – it just seems snotty not to, you know?”

The following was a mock stage direction for the elaborate scenes in Anne:

Willow: Oh, I think you pushed your way to the front long before this.
Cordelia: Hey, I can’t help …

Sometimes Buffy writers leave little jokes of their own in their scripts. The following is a stage direction for Innocence, a little nod to the fact that it costs more for extras to speak:
“A couple of soldiers pass. Xander suavely nods to them. They nod back and pass without …

Various scenes were added in to The Harvest as the episode was too short. These include the scene where Willow and Xander talk in the halls, the scene where the Master pokes out the vampire’s eye, the scene where Cordelia talks about seniors in the Bronze and the scene where …

Darla was originally supposed to be killed in the end of The Harvest when Willow threw holy water on her, but a more intresting storyline for episode seven (Angel) was needed so they kept her in the show.

Joyce’s parting words to Buffy when she dropped her off at her new school in Welcome to the Hellmouth were “try not to get kicked out”. Buffy was, of course, expelled in season two’s Becoming (Part 2).

When Angel first met Buffy in Welcome to the Hellmouth, he said that he thought she’d be taller, implying that he’d never seen her before. In Becoming (Part 1), we saw a flashback of Angel watching Buffy when she was chosen as a Slayer in LA. Angel later mentioned the …
