S3·E15 Wheels on the Bus

The Man With The Yellow Hat is running late to an appointment to show an important scientist some of his work, so he and George decide to take the bus to his appointment. But when George wanders off of the bus to get a map of the bus routes and the Man follows, leaving his work on the bus, they both wind up splitting up and each trying to find a way to find the bus and retrieve his work all while trying to arrive to his appointment on time.
