Cheburashka character named "Старуха Шапокляк" (Old Lady Shapoklyak, from French "chapeau claque", a kind of collapsible top hat). Shapoklyak is a mischievous but charming old lady. She is tall and thin, wears a hat, a dark-coloured dress, and bloomers, and carries around a pet rat, Lariska, in her purse to help her play pranks on people, though near the end of some stories she turns around and helps the protagonists. The chorus of her theme song contains her motto, "One won't ever get famous for good deeds." The rights to the Cheburashka character and image have been heavily debated in court.
Top Hat as early as 1915. There ensued a lifelong friendship with Berlin contributing to more Astaire films (six in total) than any other composer. Of his experience with Astaire in "Top Hat" Berlin wrote: "He's a real inspiration for a writer. I'd never have written "Top Hat" without him. He makes you feel so secure." As Berlin could not read or write music, and could only pick out tunes on a specially designed piano that transposed keys automatically, he required an assistant to make up his piano parts. Hal Borne – Astaire's rehearsal pianist – performed this role in "Top Hat"
