The Ghost Busters S01 E11 Jekyll and Hyde - Together for The First Time

"Spooks, monsters and ghouls got you down? The Ghost Busters will save the day!"

Dr. Jekyll and Mr. Hyde are living as two separate persons, with the Neanderthal Hyde driving insane the urbane Jekyll. Only by drinking a potion made from a person without any personality can Jekyll ever hope to be set free from Hyde.
