Yeah, first time I heard it I was at the park, and thought there was a duck around, so I took my rifle out and shot randomly, turns out I hit a lizard but no duck flew away. Then as I walked home I heard it again and thought a duck was following me and mocking my shooting skills so I dropped my rifle and ran for it. I kept hearing "quack" so naturally I freaked out. I wrapped myself in a blanket and began having odd thoughts on the possiblility that I was insane...but in the end I found out it was the song....

and that's when I knew all was right in the world
