Wonderful parody, when the Simpsons did that sort of stuff.
I had only seen it probably once as a kid (or maybe just the Fats Waller frog scenes?) but here is a controversial cartoon:
Swing Wedding is a 1937 cartoon by Metro-Goldwyn-Mayer. Directed by Hugh Harman, it is part of the Happy Harmonies cartoon series.
A “sequel” to The Old Mill Pond, the cartoon portrays a wedding celebrated by a group of frogs in a swamp. The frogs are designed as caricatures of various African American celebrities of the 1930s, such as Ethel Waters, Stepin Fetchit, Louis Armstrong, Cab Calloway, Fats Waller and the Mills Brothers.
Notes
First to be labeled as “A Hugh Harman, Rudolf Ising Cartoon”.
Though hailed as “’one of the finest one-reelers in all of animation” by some commentators,[1] others have derided the use of Zip Coon-type figures and stereotypical dialogue (including expressions such as “Who dat?” and “Yowza!”).[2] The film also contains a controversial scene in which a frog musician uses his trumpet valve as a syringe. The scene plays on the stereotype of black jazz musicians using drugs before performing.[3]
This cartoon was re-released in a shorter version called “Hot Frogs” in 1942.[citation needed|date=]
Discussion only, not the cartoon:

Guess you didn't catch my parody of Krusty. That's what he said after viewing the kartoon.🤪
