When I was a kid cartoons were only shown on Saturday morning. Many of the cartoons were the ones shown during World War II and they were really funny. I remember Mighty Mouse "knocking out" Tojo, Daffy Duck dressed up as Hitler and Bugs Bunny planting a big wet kis on Uncle Joe Stalin. All of them are now probably banned by the PC Police. Too bad.
The WWII cartoons I recall seeing in the 1950s featured the following:
Bugs Bunny outwits an entire islandful of Japanese.
Daffy Duck outwits a German antiaircraft battery (featuring a black eagle character in an SS uniform)
Donald Duck is imprisoned on a Nazi artillery shell assembly line (turns out to be only a nightmare)
Gremlins from the Kremlin rip Adolf Hitler's aircraft to shreds as he attempts to bomb Moscow in person.
Bugs Bunny confronts Hermann Goering in the Black Forest ("I knew I shoulda taken that left turn at Albuquerque")
Popeye the Sailor beats up a composite enemy with Jap features and swastika emblazoned uniforms.
(Very, very un-PC, that last one)
