But you are the place
Where all my frogs go hiding

The story:

I was listening to this with a friend, and I asked her about the lyrics, 'cause I thought I heard 'frogs', and knew that couldn't be right. But when she listened closely, she also heard 'frogs'. The more we listened, the more convinced we got that she really sang about frogs. It wasn't until a year later that someone corrected us when we were singing it out loud along with the radio. I immediately thought: "Oh, that makes sense." I felt kind of stupid that I hadn't realized before what the real lyrics were.
