I Haven't Got a Hat is a 1935 animated short film, directed by Isadore Freleng for Leon Schlesinger Productions as part of the Merrie Melodies series.

The show continues on with Little Kitty trying to recite "Mary Had a Little Lamb", but she forgets her lines, despite Miss Cud's attempts to help her out.

Two cute puppies Ham and Ex then sing a humorous love song "I Haven't Got a Hat", which earns them a standing ovation from the audience.

The result appears to be that Oliver plays a magnificently difficult piece, and the crowd applauds, but then the dog and cat run out of the piano, earning jeers from the audience.

Beans and Oliver then lash out at each other, but only manage to get covered in paint and fountain pen ink in the end, and they both shake hands afterwards.
