I can never enjoy these clips since I speak German. So I can't read subtitles that say other stuff than what the people in the clips say.
I do speak German and can still follow, because in Portugal we always subtitle except for children movies, so we learn to selectively pay attention to either subtitles or audio depending on the movie and our language skills.
As far as I am aware this happens in all countries that have a subtitles culture, instead of dubbing like in Germany.
However I am also not a big fan of these clips, given the historical relationship. Not sure how much one should actually it for jokes.
Grey area for me. It's a fictional work, AFAIK, based on some evil shit in history I generally don't joke about. The scene is nearly perfect for remixes to the point many great ones have been made with it. SO, on other hand, maybe remixing his downfall in educational and entertaining ways isn't so bad after all. :)
