Too bad that you're asking for DS titles only - I have the perfect PSP one that tops yours.

The game itself has a very compelling story and it's a must-have title... but this dialogue? It comes from nowhere and I just went "what the f*ck is this?", actually rising an eyebrow, then frowning (when a game causes a physical reaction, you know something's cooking) as soon as I read the first few lines, wondering if the subtitles team wasn't just fooling around at some point in development, made a joke and forgot to remove it from the final build by accident.
