This whole "preview discussion" thing has been brought up a few times on different shows over the years, and personally I think it's totally okay to discuss/mention stuff that is in the previews at the end, since they are actually a part of the episode.

But if people are that bothered by it i can at least try to avoid talking about them if need be. (I'm not exactly the most active poster here anyway, lol)

On the topic of names, when i heard the princess name was Piņa Co Lada my reaction was pretty much this http://i.imgur.com/R5fJOAq.gif
