After Noel tearfully says "Goodbye, Miss Freezenda, goodbye", his mouth never moves during his next line: "Gee, she didn't even say goodbye".
When Miss Freezenda is shocked at the words "chipped and old", she does not speak the second half of her line: "What does he mean by that?"
When the First Father Thing closes the lid to the box holding Noel and the other ornaments after Noel's first Christmas, he does so with the lid horizontally instead of vertically.
