Uncle Vladamir
Uncle Vladamir is Bender's robot Uncle. He dies in (episode ref needed for "The Honking") and in turn leaves his haunted Transylvania style house to Bender - on the condition Bender is not responsible for his death.
Later in the episode he reappears as a ghost, projecting himself through the abandoned modem that is still plugged in in the cemetery next to his house.
Uncle Vladamir's death is in conflict with how you would expect a robot to "die". He suffers what can only be described as old age and dies peacefully in his large bed in his mansion.
