Magic School Bus

The Magic School Bus is a bus appearing in Never-ending story. It can serve as a time machine.

Never-ending story
Albert Einstein committed suicide by being run over by a bus, possibly the Magic School Bus.

The bus went back in time to the year 5, where Hannibal Lector tried to eat everyone alive, but just looked plain stupid instead. His look was so ugly, that everyone (except for Hardink) died and became zombies.
