Answer: The "Hitler in the bunker" scene is iconic for historical reasons, being something most people understand the significance of. Being subtitled in the film means it's very easy for people to keep the original excellent acting while simply replacing the words onscreen to change the context entirely. It also ends up being a bit self-reinforcing, once people get wind of it as a "template", they then start getting their own ideas. And there's the arguable "Streisand Effect", when the film company issued a wave of copyright takedowns in 2010, a lot of people "retaliated" by making and uploading even more.
