My main problem with people saying it's *clearly* "laugh and cry" is this:
The published sheet music may be "laugh and cry", Seth may have recorded it as "laugh and cry", but guess what? Listening is subjective. If I, and many others, do not hear the word 'laugh' (or 'and', for that matter) enunciated clearly then it doesn't really matter what was supposed to be sung.
Additionally, if it was so obviously "laugh and cry" to begin with, why was that phrase re-recorded for Season 3 episodes? Because it wasn't obvious, and because it sounded like "f-in' cry". Sure, it might not have been intended to sound like that, but that doesn't mean it doesn't.
Ultimately, I am not questioning what the line was *supposed* to be, I am questioning what it actually sounds like; and there is no possible clear "correct" answer to what it actually sounds like since listening is not an objective activity.
