Lyrics question (long shot)

Sometimes my brain produces random songs to play at me when I wake up. This morning it didn't manage a whole song, just one line:

"She said 'hi', I said 'yeah, I think I am'"

I can't remember anything else of the song, and Google doesn't seem to know either. I think it might be parent-music - that would explain the feeling that I've heard it a lot, but not for a long time. Anyone got any ideas?
