Revealing mistake: In the beginning of the episode, when Buffy stakes the vampire that she beats up for a long time, watch when she lifts the stake. The hole in the vampire's chest is a solid 8" below where she actually hit him with the stake. (It's an effects shot, so somehow, they just didn't line up).
Continuity mistake: Right as Buffy gets out of the car and watches Joyce drive away, Cordelia and her friend are walking up the stairs, along with a girl in a blue shirt at the top of the stairs walking towards the school. The next shot Buffy is walking towards the stairs, Cordelia is already far away chatting with her friend and the girl is blue is back on the stairs again. (00:27:00)
Continuity mistake: After drinking the water with the virus, Buffy looks into a room and her hair is damp and brushed back. In the next shot, it's dry and parted down the middle.
Other mistake: Buffy freaks out when she's first taken to the hospital. Joyce tells the gang it was because her cousin died when they were young, but in season one episode "Angel" Buffy has no problem being in the hospital, same with later seasons.
Chosen answer: "So goes the nation" seems to have been used on many occasions, with various different US states in the "As .... goes" section. Most commonly it seems to be California that's considered to lead the way, but probably most other states have appeared in the lead role at some point or another. Other things have also been used - no less a person that Pope John Paul II said "As the family goes, so goes the nation...". The origin of the quote format is unclear - in US politics it goes back into the 19th century, when it was Maine that held the title spot, but, while no definitive origin is known, it seems highly likely that it goes back considerably further than that.
