I've been waiting a long while just to see that one episode, as seemed interesting..

And it was. Pinkie is the main reason I still watch the show now, (not that I don't LOVE the other characters, cause I do)..

There was something about dozens of Pinkie clones gathered inside Twilights building, all hoping around, liturary!
That somehow made Pinkie's character, that much cuter.

And appearently, she's aware of her cuteness, as she says it about her clones.
