Put it in your panties with your car keys

The story:

Well, I had thought it was the said lyrics for a
while. I really liked to song, and I was
humming it to my friend Fishey, and then as I
hummed that lyric, she was like, "o_O Sure. I
hide looootsa stuff there." This made me
doubt whether those were the right lyrics. So I
went to paulsimon.com, and it turns out it was
pantry and cupcakes, not panties and car keys!
So I told Fishey, and she started cracking up.
Now that's her away message!
