This post has little to do with Looney Tunes, but it DOES have something to do with classic animation. And I'm not even talking about "Scooby Doo" or even "Johnny Bravo", per se. It just serves as sort of a follow-up to the announcement of the Cartoon Network Looney Tunes marathon this upcoming New Years' Day. In its heyday, Cartoon Network had a huge respect for classic animation, and so did the creators of their original "World Premiere Toons", later known as "What A Cartoon" and "Cartoon Cartoons".
This particular cartoon short from the "Johnny Bravo" series is a brilliant parody of the original Hanna-Barbera "Scooby Doo: Where Are You?" TV series, but it also has three brilliant classic cartoon references: Keep a lookout for the reference to Disney's Donald Duck/Chip and Dale classic "Donald Applecore", and the Tex Avery "door-chase" gag from MGM's "Lonesome Lenny". If that isn't enough, there's even a reference to Joe Barbera. Sadly, in just ten years since this was made, Cartoon Network has devolved past anything this clever.
