Perhaps to make up for the lack of Foghorn Leghorn on DVD and home video, a YouTube user has uploaded twenty Foghorn Leghorn cartoons. Watch 'em while they're still there.
Foghorn is one of those cartoon characters who has remained a lot more popular than he was probably expected to be. What I mean by that is that I never got the feeling that Warner Brothers pushed him as hard, in licensing/marketing terms, as they did other characters. (In the late '40s the studio probably pushed Henery Hawk harder than they did Foghorn.) But people really love him and quote him all the time, and a Foghorn cartoon is almost always a big hit in theatrical screenings.
The thing I appreciate about the series is that it was less dependent on formula than most late '40s and '50s cartoon series. Instead of one basic chase plot, the series had a whole bunch of different "standard" plots that it could draw on: some were Foghorn vs. Henery Hawk, others were Foghorn vs. the dog, others had an outside character playing the barnyard animals off against each other, and still others had Foghorn and that uber-powerful nerd kid. You can actually go into a Foghorn Leghorn cartoon and not be completely sure what you'll get, which is not true of Tweety/Sylvester or the Road Runner. I also like the fact that at a time when cartoon violence had gotten more self-inflicted, with the villains usually bringing destruction on themselves, the Foghorn Leghorn shorts still had characters beating the hell out of each other.
Like all McKimson cartoons, the quality of the series is uneven, terrifically good at its best (in cartoons like "Fractured Leghorn" and even some of the later ones like the very weird "Fox Terror"), sort of too much like an animated sitcom episode when it's not on form. The series probably suffered more than any other McKimson series from the departure of his A-list animators in 1953. Without a first-rate broad animator like Manny Gould or Rod Scribner, Foghorn's movements became very mild and controlled, and the character became a lot less funny. (Foghorn was already starting to get milder throughout the early '50s -- he was at his best in the early cartoons when he's "just a loudmothed schnook" -- but Scribner's scenes help him preserve some of his original energy, like the scene in "Of Rice and Hen" where he practically flies apart while seeing Miss Prissy jump off the roof.)
