Not to get all linguisticy, but this clever video basically trades on a sort of quasi-McGurk effect, right? We are using both visual and auditory cues to interpret the input and when there is a mismatch, we take a best guess at some intermediate form. Whereas in the McGurk effect we are guessing at a phoneme, here we are guessing at lip formation, no? So our perception that the audio aligns with the video "pretty convincingly" is, in effect, helped along by our brains. In any case, I feel a strong desire to go buy apple juice.
I think it's interesting the recurring words in these. Here it's apple juice, fish and zepplin.
I've seen other where it's more about farts. is it a case of you see what you think about? these guys are definitely stoners.
