NBC Promo for Parks and Recreation Accidentally Releases HUGE Spoiler?

Toward the end of tonight’s episode of NBC’s Parks and Recreation, NBC aired one of their promos plugging the show’s website, as is the custom. However, the promo seemingly contained a humongous spoiler: It told viewers to log onto the show’s website for gift ideas for April and Andy’s wedding. The thing is, there has been absolutely no sign whatsoever that April and Andy would be getting married anytime soon; in fact, the two characters aren’t even dating, as Andy has been trying to win April over since last season.

I have two theories:

1. NBC released a promo for the show that was supposed to be for a future episode, thus accidentally revealing a huge spoiler at the wrong time.
2. The episode that the promo aired after featured characters Ron Swanson and his ex-wife Tammy getting married during a drunken binge, and also featured character Jerry giving them a present from their wedding registry. So, instead of revealing a spoiler about April and Andy’s future relationship, the NBC promo simply blundered and said the incorrect character names.

However, the problem with theory #2 is the above video clearly shows April and Andy when the voiceover says their names, and I can’t seem to find the wedding registry on NBC.com, where the promo says it’ll be. Whatever the reason, it looks like NBC just made a pretty big blunder.

UPDATE: Going with theory #2, the show’s website finally updated with Ron and Tammy’s wedding registry, though it seems to simply be 11 stock photos of nothing related to the show, nor anything comedic. It seems entirely possible that NBC realized their blunder, then quickly threw a Ron and Tammy wedding registry together in an attempt to cover their tracks; however, as the above video clearly shows, both April and Andy are shown on screen when the voiceover says their names in the promo.

UPDATE 2: On the April 14, 2011 episode that just aired, Andy and April actually did get married. It looks like NBC really did accidentally release a huge spoiler back in February.
