Continuity mistake: When the team are gathered round the table at the beginning of the episode, note their positions when the video screen is turned on. When they see Fry drying his hair, Leela and Bender have each moved up a chair, and Zoidberg has also moved, and seems to have taken half of his previous chair with him.
Continuity mistake: When Bender sits beside Fry on the couch, Bender's sitting at the end with his arm on the rest. When Fry says 'Leela, we're trying to watch TV' Bender's moved to the middle of the couch. The garbage next to Fry and the contents on the table also change in this scene.
