Beer Bad - S4-E5

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.

Visible crew/equipment: When Buffy, Xander and Willow get up from the table, the personal microphone equipment clipped to the waistband at the back of Xander's pants is visible; he adjusts his shirt to cover it as they turn to walk.
