Someone please tell me I'm not crazy on this. I thought it was dumb when I heard about it too but then someone forced me to listen and I honestly thought they were messing with me. They heard Laurel all the way and I couldn't even process how that was possible because I heard Yanny and nothing even close to Laurel. Finally I found a clip that slowly increased the pitch and I heard both. It's actually pretty crazy because different people will hear both in this but they will one or the other at different pitches than the person they're listening with. See for yourself. Listen with a friend.
