I know we're only half way there
But there's a baby on the way, a baby on the way

The story:

I hate Maroon5. But these were the only "lyrics" I could make out of this song when I first heard it, and I thought they were really sweet, the guy being happy about his new kid about to be born. Then I listened to the rest of the lyrics and was like, "Um, really? That's not cool!" I actually had to go and look up the real lyrics because I knew I couldn't be right.
