As part of his late uncle Vladimir's last will, Bender must spend the night in his family's sinister old castle near Thermostadt, the capital of the Robo-Hungarian Empire, in order to inherit it.
However, the castle's holographic "robot ghosts" cause him to flee out into the night, where he is run over by a mysterious non-hover car.
After returning to New New York, Bender begins to experience nightmares and blackouts, and believes that the car has followed him home.
Calculon's claim that he was all of "history's greatest acting robots" is a subtle reference to the immortal Mr. Flint from the Star Trek: The Original Series episode "Requiem for Methuselah".
I was especially fond of the ultimate source of the were-car problem, a murderous vehicle built by a group of scientists for Project Satan.
