For what it's worth:
The third Fox airing (or, in some cities, second, after the premiere was preempted for speeches) of this episode, 2/24/13, actually matched the first airing, with a clouds-only opening and pre-credits inclusion of the "fiscal cliff" bit. Odd, especially since we avoided the cliff, though this week we had to deal with essentially its postponement to the "sequester" (if I have my politics right and I may not).
The rating was PG-LV, though the second airing was PG-LSV. I don't know what the original was.
