Discussion: What Parts of Season One Amazed You?

It's time to think wayyy back to months ago when brand new official content was gracing out monitors and TV screens.   If you came from /co/, the best part of the week was always the thread during, or right after, the official airing of a new episode on The Hub.  The amount of 20+ year old's squeeing like 12 year old schoolgirls over every little detail was beyond entertaining.

I'm pretty sure most of us went nuts when Derpy Hooves first popped up during Feeling Pinkie Keen, but what else made you blow your mind?
