Rat Pfink a Boo Boo was a very low budget 1966 film directed by Ray Dennis Steckler and starring Carolyn Brandt.

Why the title is "Rat Pfink a Boo Boo" and not the more logical "Rat Pfink and Boo Boo"? According to legend, that was indeed the intended title, but when the artist creating the titles made an error and rendered the "and" as "a", Steckler's budget would not stretch to the $50 needed to fix the mistake. According to Steckler, however, the choice of title was deliberate: "The real story is that my little girl, when we were shooting this one fight scene, kept chanting, 'Rat pfink a boo boo, rat pfink a boo boo ....' And that sounded great! But when I tell people the real story, they don't wanna hear it, so you better print the legend."
