Continuity mistake: Willow's hair changes position between shots when the vampire brushes her hair back and kisses her.
Continuity mistake: When Veruca comes to Oz's cage to spend the night there, she tosses her jacket onto the round stone thingie (knob?) at the end of the stairs, and it covers the whole thing. However, when Willow discovers them in the morning and Veruca goes to pick up her jacket, you can see that it has moved. Willow didn't touch it when she entered, and both Oz and Veruca were locked up so they couldn't get anywhere near it. (00:26:35 - 00:29:20)
Continuity mistake: In the season two episode, 'When She Was Bad', in the scene where Buffy smashes the masters skeleton with a sledge-hammer she smashes the rib cage to pieces. Suddenly the rib cage has again become completely intact and she smashes it to hell again. (00:40:35)

Continuity mistake: When Cordelia comes up to Buffy talking about how "even slaves get minimum wage", in pretty much every shot her arms switch from being at her sides to crossed in front of her, held behind her or on her hips.
Continuity mistake: When Buffy fights the guards and says, "Anyone who isn't having any fun here follow me," the top under her jacket is purple. In the next shot, when she turns to walk out, it is green, then back to purple when we see her again.
Continuity mistake: When Xander is showing Willow and Buffy his fake ID and the view of the shot is from behind Xander, he is holding the card with his thumb and middle finger. Switch to the view from behind Willow and it's being held with his thumb and index finger. Then it switches to behind Xander again and it's back to thumb and middle finger.
Continuity mistake: Towards the end, when Buffy stops the arrow, when she first grabs it her hand drops down to Cassie's mouth level, and her arm's bent at the elbow. When we cut to another angle it's now held at arm's length and at about eye level.
Continuity mistake: When Joyce is talking to Buffy about the shadow, after she says "sometimes weeks", she turns towards Buffy. In the next shot she's facing away from her, then turns to face her again. (00:10:55)
Continuity mistake: In the basement scene, with Jack and Xander, the bomb counts down from 13 to 10 seconds. Then after Xander says his line, the bomb again shows 13 seconds.
Continuity mistake: In "Becoming Part 2" At the end when Spike chokes Drusilla unconscious, he picks her up, one of her hands is resting on her stomach and the other is hanging to her side. It cuts to a shot of Spike looking at Angel and Buffy fighting then to Spike leaving with his back facing the camera. You can see that the hand resting on Drusilla's stomach moved to Spike's shoulder.
Once More, With Feeling - S6-E7
Continuity mistake: During "Something to Sing About, when Buffy sings, "You don't get to rehearse," Tara walks past the support pole behind her. In the next shot from an angle, she's closer to the middle of the room and the pole is not visible. (00:41:40)
Continuity mistake: When Buffy puts her egg down, the position of the chain and pen she sets it down by change depending on whether the shot's from Willow's side or Buffy's. (00:08:40)

Continuity mistake: When Glory challenges Dawn to name one person who can cope with life on earth, there is a close up of Dawn answering "Buffy". In this shot, the black mark (where she has been annointed) that is there before and after, has completely disappeared. (00:24:05)
Once More, With Feeling - S6-E7
Continuity mistake: When Buffy is singing "Something to Sing About", she sings the verse beginning 'All the joy life sends, family and friends', and we see that Anya and Tara are stood in the background, about 3 metres apart from each other. However, for one shot, they appear less than 1 metre from each other. (00:42:05)
Continuity mistake: In Graduation Day Part 1, when Faith and Buffy are fighting, Faith throws Buffy into the wall near the TV, but the TV is intact. A few shots later, there is debris on the floor, glass and such, from the TV, and when it's shown again, the TV is unbroken. This happens a few times. In Graduation Day Part 2, when Faith and Buffy are talking in the apartment, the TV is broken again. (00:38:05)
Continuity mistake: After Buffy slams the Gavrok spider thing on the ground with her back, she gets pulled up by Angel. We see this shot from the back, and we see that the Gavrok is no longer on the floor or on her jacket. In the very next shot, we see Angel kick it across the floor. Where did it come from?

Continuity mistake: When Buffy is hitting the punching bag near the end of the episode and Riley comes in she has bandages wrapped around both her hands but in the close up shot there is only a bandage on her left hand.
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
