Just watched this episode last night. Enjoyed seeing the contrast between the animation styles and characters from the pilot until now. And the time travel stuff was pretty funny. However, after the second time Brian and Stewie came back from Jan 31, 1999, why did they have Lois say that Brian had written the Harry Potter series? That would only make sense if the series had been entirely written after that date, but the first book was released in 1997, so that joke makes no sense.
