I wonder who invented "ew"? People didn't say "ew" thirty years ago. Somebody had to be the very first person to do it. Talk about unsung heroes. They're probably laboring in obscurity somewhere, all bitter and whatnot for not getting the recognition they so richly deserved. I'd like to find them and ask them how they did it. Did it just come to them spontaneously, or did they have sheets of notebook paper with hundreds of odd sounds written on them, most of them crossed out? This is just one of the many things I wonder, so you don't have to.
