What is your funniest "musical epiphany"?

I’ve been listening to Norah Jones for years now and one of my favorite songs by her is Man of the Hour. I’ve heard this song countless times and I always thought it was a sweet song about a great (human) love. Well, imagine my surprise when I suddenly realized that, all along, she has been singing about a dog! Now, every time the song comes on, I can’t help but laugh at myself for having taken so many years to figure out what she was really singing about, despite always puzzling over the fact that the song ends with a dog bark.

Do you have a similar story you’d like to share?
