Death by Resurrection - S1-E12
Continuity mistake: McBride and Ryan are driving through town in heavy traffic. When the shot cuts (and their conversation continues uninterrupted), not only does the rear view mirror disappear, but an obvious rear screen projection changes their locale to a country road with trees and no traffic at all. (00:06:00)
Continuity mistake: The package containing the camera changes size and shape between the opening scene, where Barnes drops it into a mailbox, and the scene where it arrives at Auden's office.
Continuity mistake: During the car chase, Ryan pursues the kidnappers up a hill past two parked VW vans. When the camera angle reverses, one of the two vans has disappeared. (00:12:15)
Continuity mistake: At the carnival, Pete's cotton candy changes shape and doubles in size between takes. (00:24:30)
Whatever Happened to Carol Harmony? - S2-E23

Ain't Nobody Here Named Barney - S1-E17
