MST3K Ep. 912 - "The Screaming Skull"
(Short: Robot Rumpus) Newly married wife Jenni can't tell if the skull she sees in her new home is a ghostly apparition of her husband's dead first wife, or just hallucinations from her own nervous condition ... or something else.
The short is a Gumby cartoon.
This episode was the last rerun ever shown, on January 31, 2004, more than four years after new shows ceased.
