Triumvirate of Terror! - S3-E8
Continuity mistake: After the opening title sequence, it shows Batman and a reporter tied to a giant bullseye target. She and Batman are equal distance from the center bullseye, and it is about waist level on her. It then cuts to a perspective from Batman's angle, and suddenly the reporter is much closer to the center, and the bullseye is level with her calves. Then when the giant pie is flying towards them, the center bullseye is level with her and Batman's feet. (00:05:05)
