I thought the end would tie up the story of his father ("Say Hi to them from me") and his own family, especially since he seem to be rather estranged from his wife and son, even though they were there on his big day.
The final joke was good, but seemed a bit out-of-nowhere, and therefore unfitting to the rather serious tone of the submission so far. But I liked the animation nonetheless, a bit rough sometimes, but a touching story told in a very capable way.
