Corrected entry: Both young and old Stewie don't seem to know how human reproduction works. Yet in the episode where Peter and Lois decided to have another baby Stewie understood the biology well enough to shrink a ship and fly into Peter to destroy his sperm, implying detailed knowledge of the system.
Question: When this came out on DVD, the box said it was uncut and uncensored. So why was all of the swearing censored?
Answer: There are two versions on the disc. From the main menu you can go to a sub menu that allows you to choose which one you watch.
How do I find it? I've been looking and can't see it anywhere.
The only thing it lets me choose is subtitles and different languages.
Have you looked in the Languages menu? It should let you select the uncensored English audio track.
Correction: This episode could have happened after the movie, since it isn't established where the movie fits in the timeline of the series.

The movie is divided into 3 episodes placed at the end of season 4. The episode "Emission Impossible" is S3 E11, which is before the movie.
Whether this episode occurred before or after isn't relevant because that's doesn't explain why old Stewie doesn't know if at some point his younger self knew.
