Noodles on a Bike

It's a song by Sheryl Crow.
I've been singing it on Y92.5 for as long as I can remember.

Well, last Friday I had to pick up Cristen at school. I drove my mother's car to save my gas and she, of course, was listening to Y92.5, like always.
So I pick up Cristen and Sheryl Crow's "My Favorite Mistake" starts playing. Now, my sister and I are not very good singers, but we sing along anyways and I notice that my sister and I are not singing the same chorus.
So I ask her what she's saying and she replies:
"Did you know when you go it's the perfect ending,
to the bad day I'd gotten used to spending.
When you go, all I know is you're my favorite mistake
You're my favorite mistake. "

And I feel really dumb.
Because I didn't know what that the song was called "My Favorite Mistake" and I thought the chorus was: "When you go, all I know is my ferret must stay/Yes my ferret must stay."

Yeah.
Don't know if I'll ever live that one down.
