While Friz Freleng's "Malibu Beach Party" does contain racial stereotypes, it's pretty funny otherwise. It depicts a party held at the Malibu home of Jack Bunny (an obvious parody of radio star Jack Benny), attended by the top stars of the era. An example of a gag is that Greta Garbo (or her caricature) uses her over-sized feet as a surfboard.
This was not the first time that a Jack Benny caricature had appeared in a Warner Bros. cartoon. "I Love to Singa" portrayed a rabbit - no relation to Bugs Bunny - named Jack Bunny, hosting a talent show. But probably the most famous animated version of Benny is "The Mouse that Jack Built". That one casts the characters from "The Jack Benny Show" as mice, and they all provided their own voices.
So anyway, this one isn't great, but it's still worth seeing.
