Proverb: “Волга впадает в Каспийское море”
Phonetic: “Volga vpadayet v Kaspiyskoye morye”
“Yeah, and the Volga empties out into the Caspian Sea”
Meaning: This proverb is used in a sarcastic way, as a way to signify that you are stating the obvious.
Background: This is used between any people in Russia, and references their formal geographic education, which is very strong in Russia and is sometimes mocked because it often lacks practical uses. In addition, Russian formal education often focuses on rote memorization of facts, and knowledge like this would be an example of pointless information that nonetheless everybody knew.
Analysis: This mockery of the redundant brings attention to the Russian value of brevity and modesty: at least in respect to not showing off useless facts. Russian humour is often wry and employs irony, so overstated or over-important people will often find themselves mocked. At the same time, the fact that everybody knows a fact like this is a reference to the fact that Russia is such a huge land that learning all of its geography is something many students resent. Comparing such unwanted knowledge, which is also commonly known, is more likely to make the person stating a different obvious fact feel ashamed, and likely feel like a teacher or authority figure. These figures are not usually seen favorably in Russian society on the part of those who they teach or are supposed to control.
