Whenever one sees a list of the worst movie titles in history, invariably you'll see these two sub-B movies (they usually sprout up on lists of the worst movies period too): The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies!! and Rat Pfink a Boo Boo.
Billed as "the world's first monster musical!", the former (a cautionary tale for young men to not get involved with vengeful carnival fortune tellers) has also gone by the not-an-improvement titles The Teenage Psycho Meets Bloody Mary, Diabolical Dr. Voodoo and Cabaret der Zombies.
As for the latter (a low budget spoof of the 60's Batman TV series), the title was actually supposed to be Rat Pfink and Boo Boo, but when the original prints were delivered, it was discovered the title designer left off the "n" and "d". The filmmakers couldn't afford to correct it, and a bad movie legend was born.
Both movies will air tomorrow morning on Turner Classic Movies as part of their TCM Underground series of cult favorites.
