Twilight decides to explain what fun is to Luna in the best possible way. I kinda wish Pinkie hadn't been running away so much, this would have been PERFECT for her. Oh well, Twilight will have to do.
If you don't know what this is referencing, (I'd be surprised if you didn't), but just in case its the 'Fun' song from Spongebob. Go look it up, its awesome!
EDIT: wow, only 13 hours later and I've seen about 4 or 5 other places making this joke, I knew it was quite obvious but wow. Note to self: Be more original in future.
