There is a movie about Hitler with a scene that is now famous; he's in the bunker, the Allies are closing in, he knows the war is lost, and he begins ranting at the top of his lungs. The movie is in German, with English subtitles. That scene has been spoofed in a dizzying number of ways, by inserting different subtitles. Hitler rants in German, but the English words change.
I've seen several of these versions now, and all of them are funny. But the one below is by far the funniest. Warning: the subtitles contain a considerable amount of profanity. But, quite honestly, that makes it all the funnier. I nearly coughed up a lung the first time I saw this.
