Bus 23

"You know anything about...Bus 23?"

- Lisa Simpson

Bus 23 was a bus used by Springfield Elementary on a field trip.

History
Otto, the driver of the bus, lost control and the bus ended submerged underneath the top of the icy waters of the river. Years later, Lisa Simpson, a Springfield Elementary student, found the bus in the bottom of the river after falling from a Duff blimp. When the bus rose to the top of the water, she found the bus was filled with mannequins, because the school needed to rid an abandoned classroom of the objects, as they needed to be returned to the factory, otherwise the school would be charged for the extra day of keeping them.
