The Demented Hills Asylum, also known as the "Demented Hills" or "D.H.A." for short, is a fictitious hillside mental institution in the 1997 Nickelodeon comedy movie Good Burger. This hospital is used to restrict the mentally disturbed for the safety of themselves and of the general public for 75 years since its founding in the early 1920s. Later that Otis was taken away to Demented Hills after stumbling upon Kurt's new plan to sabotage Good Burger with shark poison. He too has been thrown into the same padded cell with Ed and Dexter.
