Character mistake: In "Boobs In Arms" (1940), the Three Stooges are in the Army. On the back of Curly's uniform is an advertisement for "soup, salad, entree, coffee, desert" at O'Brien's Kosher Restaurant. "Dessert" is misspelled.
Character mistake: In "Movie Maniacs," the Three Stooges arrive in Hollywood via train, sneak into a movie studio and walk onto the set of a movie being filmed. A starlet looks at Curly and says, "Oh, Mr. Howard." There is no way she could have known his name.
