Sydney, at the top of her lungs, was doing a mirror-breaking rendition of this:
Jaycob (my oldest) then recounted the following conversation he had with Ashton while playing with their army men:
Jaycob: Hey, your guys can't fly. They're not even on the buildings.
Ashton: Yes he can. (In his pretend army man voice) "I'm Mary Poppins"
Ashton then had the army man float from one building to another as though he was carrying an umbrella and carpet bag.
This just disproves my theory that they really weren't paying attention to the movie. As well as enforces the idea that with a carpet bag and an umbrella, pretty much anyone can fly.
