You Can't Win is the fourth episode ever made in Season 4.
Duke is feeling poorly and Stuart jokes that he and Falcon may have to keep him in order. Duke pays no attention, but when he is taking his passengers home, he starts wheezing and Falcon and Stuart have to help him. The three split up at the next station so Falcon can take Duke's to the docks and Duke and Stuart can take Falcon's train home. Stuart is delighted, but Duke is not quite out of steam and makes a grand effort. At the top station, a man tells his son that Duke had to help Stuart, who furiously disappears in a cloud of steam.
- How could Duke appear next to Stuart when Duke was coupled behind him?
