La busta scomparsa

One day George is walking the street of his apartment building trying to find something to do when he notices a woman leaving numbered boxes outside every building. He decides to be a helpful monkey and return them to her until his friends Steve & Betsy tell him that she is a postal worker and that leaving boxes for people is her job. So they go on a race to see who can finish returning packages first. Winner plays Steve's video game. Steve has a plan to simply run fast but George and Betsy come up with a plan to sort all of the packages by the number of the buildings they go to.
