The Panopticon/Production in-jokes and T:NO RW

Policy question, here. Example first, then the question.

Here's the conundrum. In The Angels Take Manhattan, the production team mocked up a New York newspaper with the headline Detroit Lions Win Superbowl. The difference from the real world is notable because 1) Detroit's famous amongst American football fans for choking - they've never even made it to the Superbowl, 2) the Superbowl winner would never be an NYC front page headline while the trees are all green in Central Park. I also am pretty sure that 3) many, many Doctor Who fans won't know this.

It's a fair bet that the show will never clarify how the Super Bowl is different in the DWU, not the least because the league is very protective of that trademark. (Unaffiliated advertisers have to use a euphemism, like "the Big Game".)

In any case, the observation was stated to be removed first as not notable, then when moved, because of T:NO RW. The information isn't being presented to say that the DWU is wrong, but to explain the significance of the choice of team where otherwise it wouldn't be known. It's background information, and it's episode specific. And it's relevant because somebody made a choice that wasn't just "look up last year's winner" or "make up a team".

Sometimes the significance of references need to be pointed up by their difference from RW. If it doesn't belong here, where does it?

There has to be an appropriate place for this type of observation. It already was in a behind the scenes section. Should it be a story note? A behind the scenes on it's own page? (Seems silly to me to require all that for a brief non-UK cultural reference.) Is the consensus of policy on this really "not on this wiki at all, ever?"
