Continuity mistake: When Ford and Arthur are looking through the bins aboard the spaceship, the fourth bin's lid closes by itself when the camera angle changes.
Continuity mistake: When Arthur is aboard the spaceship, his hair style has changed from the style he had when he was in his house and the pub earlier in this episode.
Continuity mistake: Ford's hairstyle is noticeably both longer and curlier in this episode than in the previous one.
Chosen answer: That seems to be an error in the subtitling of the episode. What Marvin actually says is: "I may just be a menial robot, but I'm far too intelligent to expect to think of me for a moment... far too intelligent..."
