The US Army Signal Corp made 26 Private SNAFU (Situation Normal All Fucked Up) cartoons to educate and entertain soldiers on behavior overseas.
The brainchild of Dr. Seuss and voiced by Mel Blanc (Bugs Bunny, and pretty much any other cartoon voice you heard growing up), these old fashioned cartoons hit on the important subjects: spies, alcoholism, stereotypes, and, for this one in particular, the old addage 'Loose Lips Sink Ships.'
The National Archives has another one posted on their YouTube channel, which is also pretty classic (http://www.youtube.com/usnationalarchives).
If you're so inclined, I'll shamelessly plug their Facebook page, too (US National Archives) because some of the posts are just damned interesting shit I've found there, and it's stuff I think a taxpayer might be interestd in knowing about strange, odd US History.

I will never read Dr Seuss the same again. I wonder if he felt pressure because of his German sounding name to create the film?
