Merrie Melodies - Pigs in a Polka (1943)

Pigs in a Polka is a 1943 Warner Bros. Merrie Melodies cartoon series directed by Friz Freleng. The short was released on February 2, 1943.
The film is a parody of two Walt Disney films: 1933 Three Little Pigs and 1940 Fantasia. The familiar story of the Three Little Pigs is set in this film to several of Brahms' "Hungarian Dances", specifically No. 5, No. 7, No. 6 and No. 17 which appear in that order. It is also part of a light-hearted, culturally subversive Merrie Melodies running joke, which would later be re-emphasized with another Fantasia parody, 1943's A Corny Concerto. There is very little dialogue in the cartoon aside from the Big Bad Wolf's introduction of the story and the pigs introducing themselves.
It was nominated for the 1942 Academy Award for Best Short Subject: Cartoons.

Notes:
All the three little pigs look like Porky Pig, but are not the same character.

Friz Freleng would create another musical-based parody of the classic Three Little Pigs story later in 1957 as "Three Little Bops", where unlike this cartoon which is based on classical music, Three Little Bops is based on hip jazz music.

Short clips from this cartoon appear in the opening credits of the Futurama episode "Mars University", in the Everybody Hates Chris episode "Everybody Hates Gretzky", and in the movie Training Day.

This cartoon entered the public domain in 1971 after United Artists failed to renew its copyright in time.

Despite the original titles being known to exist, the film with original titles has not been released on any home video or streaming service as of 2021.

The old bottle design of Lusterine Mouthwash was mentioned after the Big Bad Wolf tried to blow the house down, it was a parody of Listerine Mouthwash.
