A YouTube clip? Was it altered, maybe? Base your claims on the DVD version.
Those of you in the Bay Area of California may have been to the wonderful (!!) science museum called the Exploratorium, and you may recall their language exhibits (making random sentences, forming mouth shapes to create different vowels, etc.) One exhibit was a recording of a single word, recorded over and over, endlessly, and they asked you determine which word you were hearing. Well, nearly everyone hears something different, and it's never the actual word, because that word is a nonsense word (
fnish, if I remember correctly.) What's odd is that once you know what other people have heard, you can hear that too. You can also hear the actual word, and in the weirdest effect,
you can choose what you hear - you can make the sound into alternate words in your head, as you wish). It really freaked me out how open our brain is to perceptions, and how much control we have over our own perceptions. It's a lot like the images that have two interpretations, and you can see both. Same thing works for sound.
