If you are a small child, or if you are a jazz fan, or dear sweet Mother of God, if you are a jazz fan with small children, you need to watch this classic Looney Tunes short.
It's called "The Three Little Bops," and it just goes to show you what can happen when you give three hip cats like Friz Freleng, Shorty Rogers and Stan Freberg a sufficient budget. (Full credits here, courtesy of IMDB.)
Real gone, man.
Hat tip: Pistol Wimp.
Update: And Chap hips us (in the comments) to a link to the Tom and Jerry classic, "Solid Serenade," from the 1940s.
