George feels he's let Mitzi down when a box of chocolates he delivers to her has melted, due to him taking too long on his rounds. George feels he needs to be a faster postman, and so tries various schemes to speed things up: he gets fitness training from Archie, and tries out a pair of smart trainers from Sammy's shop. Nothing seems to help. Buster suggests a skateboard, and George is thrilled.
Now George delivers the post so early that everyone is still asleep in bed! George is unhappy: though he's faster, he doesn't get to see anyone. Frank and Buster assure him that if he goes back to his old routine, he'll see everyone again, and that everyone will be happy. Sammy even promises to help out with any future chocolate deliveries! Things get back to normal, and George realises that there are more important things than being fast.
