In the South Park movie, there's a scene where the kids try to do online research on the fabled clitoris. They inevitably end up on a porn site called "German Sick Fetish Video" with a scat fetish video playing that features Cartman's mom. The audio from the video is (mock) German ("Here I scheiß again!, "Essen meine Scheiße!") and Stan reacts by saying "Dude, what the fuck is wrong with German people?".
The German release/dub of the movie still contains this scene, except now the joke's at the expense of the British. The audio of the scat video is changed to a male voice with a cockney accent saying "Swallowin' this, ya cunt", "Eat my poo poo" and "Now gobble it up and swallow it!", and Stan exclaims "Alter, was zum Teufel ist los mit diesen Engländern?" (Dude, what the hell is up with those English people?).
