I don't know whether this is true or not, but Chris L once said that Walter's freakout in TV version of The Big Lebowski was overdubbed as "This is what happens when you find a stranger in the Alps!" I still like to think about that sometimes.
EDIT: The original line was, "this is what happens when you fuck a stranger in the ass," just in case there's anyone on here who hasn't seen the film hundreds of times.
