I’m trying to understand the premise of this joke. Are there people in the Russian Federation, even the southern parts, who don’t know who Felix Dzerzhinsky was?

The movie (Den Vyborov – Election Day) is hillarious. I’ve watched it several times already. In this scene Kamil (played by Kamil Larin) is bluffing his way out of a situation by claiming to be FSB officer Felix Dzerzhinsky. Wouldn’t that be like someone in the U.S. trying to bluff his way out of a situation by claiming to be FBI officer J. Edgar Hoover?

In any case, it’s great fun to watch. I can even follow some of the conversation, though there are many words I don’t know that I presume wouldn’t be appropriate for all social situations.
