One of these days I'm going dance with your little fishies

The story:

As a teenager, I'd been heavy into classic rock. My freshman year of college I brought out my 300 album record collection to the west coast, and my friends dug deep into my collection. We listened to this song over and over, debating the actual lyrics. I'd won over some support including some who could hear it both ways, like it was an Escher painting.
