Once when I was in college and we had an international fair, the Russian section had a Soviet-era poster saying "Ne boltay!", meaning "Don't gossip!". I "translated" it for the "generation" of TV watchers as "Don't be Gladys Kravitz!" (in reference to the nosy neighbor on "Bewitched").

However, when you see the result of gossip in the Pvt. Snafu short "Rumors", you see that it's not quite a laughing matter. In this case, the perpetually witless soldier overhears something about bombing and immediately assumes that the Axis Powers have attacked the United States. So, he tells it to someone, who tells someone else, who tells someone else, and it continues. As in "The Russians Are Coming, the Russians Are Coming", the story gets blown more and more out of proportion each time, so that when it gets back to Snafu...well, you know what I mean! Yes, it's mostly WWII propaganda - complete with a derogatory term for the Japanese - but I have to say that the Pvt. Snafu shorts were actually quite funny. Of course, since they had Dr. Seuss writing and Mel Blanc providing the voices, it's no surprise that these came out rather cool. Worth seeing.
