Education for Death. (YouTubefilter.) Disney-produced anti-Nazi cartoon short from 1943. Look for Hitler's Satanic horns. More weirdness from WWII: Warner Bros Snafuperman, starring Pvt. Snafu (originally created by Dr. Seuss!), who also deals with spies, all while jabbering away in a voice that sounds disconcertingly like that of a certain cwazy wabbit. From Archive. org -- Pvt. Snafu learns about booby traps, in one case literally. Bugs himself joined the Air Force, and was faced with gremlins for his trouble. Superman himself got in on the act, battling Japoteurs. After all, during the War we were plenty worried about those canny Japanese.
So BoingBoing recently linked to this fantastic comic book serial from the 60s entitled "This Godless Communism," a surprisingly in-depth (and hilariously slanted) history of the rise of the USSR, its leaders, and their philosophies. It's great, but it is far from the only thing on the site, the Authentic History Center. Just looking at the other comics and cartoons they have, there is a huge amount of ancient political cartoons, fantastic WWII-military-themed comic strips(surprisingly good!), and generally awesome period-relevant comic book covers, some of which link to full comics (Donald Duck's Atom Bomb?!). There is a collection of embarassing shows of race-sploitation in comics in the 70s, and the racist toys and artifacts section would make Archie Bunker blush (Chop Suey Specs!). Guaranteed to make you wince and chin-stroke simultaneously.
"Want to get arrested? Walk home with me." It's LawForKids, the site devoted to giving the kids the education they need about drinking and other kewl stuff through the aid of really, really, really crappy cartoons. Plus, enjoy the intellectual and grammar-rich discussion on hard knocks in Juvie, plus Flash games about being a good citizen. Not sure about discouraging kids from crime, but I sure as hell want to stay away from a life of web design now.
Cartoon Network has taken some heat lately for being too P.C., even here on MetaFilter. Well, here's their chance to redeem the network. Sunday evening, 9:00 - 10:00 PM Eastern/Pacific, ToonHeads Goes To War, including four rarely-seen wartime cartoons in their entirety: "Blitz Wolf" where the three little pigs face off against a treaty-breaking, German-speaking wolf; "Scrap Happy Daffy" featuring Daffy promoting the recycling of scrap metal and butting heads with a goat that bears a striking resemblance to Adolf Hitler; "Herr Meets Hare," where Bugs Bunny tangles with Nazi minister Hermann Goering; and in "Russian Rhapsody", a plane full of "gremlins from the Kremlin" attack a bomber piloted by the Nazi leader himself.
