I can't believe I watched that whole thing. When someone is speaking perfect English then suddenly says a single word in a language I don't recognize, I somehow lower the volume of the unknown word when I hear it. I could not tell if the video was corrupted or if I wasn't hearing it properly, at first. Let me be clear: I'm not making any negative comments about languages that aren't English! I'm just surprised that I watched the entire video given that I was so confused through the entire thing.
