Two things I noticed

When presenting the electronic comic book, the line "the child decides" was a cue for the child in Hanks to want to go home.

And the very end, when he and his friend walk into the distance, they say something like "you just gotta get used to a thick bat", and they laugh, it's a joke about him having a man sized penis a week beforehand.

I never got it, or did t pay attention.
