The Blue Racer is something of a guilty pleasure for me. It was a series produced by DePatie-Freleng that was theatrically released from 1972 to '74, long after television became the dominant medium for cartoons. In fact, after Walter Lantz shut down in 1972 DFE became the only major studio making theatrical cartoons.
While they made late in the theatrical era (really, it was pretty much over by then) Blue Racer never had much TV airtime in the States, although its a different story with international broadcasts. This may stem from the fact that early shorts featured the snake chasing after the Japanese Beetle, whose face is a rather politically-incorrect Japanese caricature seen in many World War II cartoons.
Halfway through the series the Beetle was dropped from the films. Later cartoons had the Racer in situations like trying to win back his girlfriend, encountering a pair of leprechauns, and adopting a baby dragon. In two cartoons they tried to get the snake back to his roots by having him chase a bee instead.
Despite being a minor part of the studio's history David H. DePatie once said in an interview that The Blue Racer was one of his favorites, alongside the Pink Panther, The Ant and the Aardvark, and the Tijuana Toads.
This is one of those later cartoons, where the Racer encounters a bear who talks like W.C. Fields. Fields (1880-1946) was caricatured in cartoons even into the sixties, with the likes of Merlin the Magic Mouse from Warner Bros. and Stanley the Sorcerer from Paramount's Honey Halfwitch. In addition, Larsen E. Pettifogger still appears in comic strip Wizard of Id.
