Wheels on the Bus (S03E15)

The Man With The Yellow Hat is pressed for time as he needs to present his work to a notable scientist, so he and George opt to take the bus. However, when George steps off the bus to grab a map of the routes, the Man follows him, inadvertently leaving his important work behind. This leads to a chaotic separation where both must navigate their surroundings to locate the bus and retrieve the forgotten work, all while racing against the clock to make it to the appointment on time.
