Deliberate "mistake": While it is established that Angel doesn't age, it's obvious across both Buffy and Angel that David Boreanaz gets older. More unavoidable than deliberate, but still worth noting. Submitted by Cubs Fan

Across whole show
Welcome To The Hellmouth (1) (series 1)
Witch (series 1)
Teacher's Pet (series 1)
Continuity: When Buffy finds Dr. Gregory's glasses on the lab floor she places them on the table, from the long shot she places them at the left end of the table near a plastic tub with a white lid, with the glasses open. Then it cuts to a close up where they are in front of a book on the right side of the table and are closed. Then cut back to the long shot and they are in the original place.
Never Kill A Boy On The First Date (series 1)
Angel (series 1)
Continuity: When Darla is spying on Buffy and Willow in the library, her reflection is seen on the side of the bookshelf. Submitted by Issabee
I Robot, You Jane (series 1)
Continuity: Buffy's birthdate starts at 1979. In "I Robot, You Jane", when the demon pulls up Buffy's file in the school system, it shows her year of birth as 1979 and that she is a senior. But when her file comes up on the student's computer screen, its changed to 1980 and sophomore. It wasn't until towards the end of season 1 in "Nightmares" that her birth year is 1981 (on her tombstone before she comes out as a vampire.)
Nightmares (series 1)
Out Of Mind, Out Of Sight (series 1)
Visible crew/equipment: At the very end, as the invisible girl gets taken along a corridor by the FBI agents, check the top of the screen - a boom mike creeps in as the agent says his line, then is withdrawn. Submitted by Jon Sandys
Prophecy Girl (series 1)
When She Was Bad (series 2)
Revealing: When all the vampires are saying "for the dark", and one gets staked, there's a mark on his shirt where the stake's about to come through before it actually happens. Plus Buffy's hands are in the wrong place for her to have pushed that stake through anyway. Not only that, but the mark isn't even close to the vampire's heart to begin with. Submitted by Jon Sandys
Revealing: When Buffy sets the vampire alight, his face suddenly gets very shiny, showing the fireproof gel that was applied to the actor's skin. Submitted by Jon Sandys
School Hard (series 2)
Continuity: 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. Submitted by Jon Sandys
