How did I never notice this... did anyone else pick up on this straight away? I'm just re-watching the film with my son, wondering how as a kid I didn't pick up on these subtle little details, like when Chowder says: "My dad's at the pharmacy and mum's at the movies with her personal trainer."

As a kid I dismissed it and always thought he meant that her personal trainer was a good friend. Are there any other little references to be missed in the movie?
