I have to say, I love this episode. Not only does it highlight all of the antics of Pinkie Pie at her finest, but it's one where Pinkie Pie actually
learns something.
Throughout the series, Pinkie has been more of a narrative force than an actual character for me. This is due to a simple fact; she's almost never wrong. To me, a character needs to have flaws, to make mistakes, to grow. The only time we've ever seen Pinkie be flat out wrong is Party of One and now, this episode.
(For example: Feeling Pinkie Keen. Twilight tries to find out how Pinkie works. Eventually winds up admitting defeat, saying that she doesn't know. Pinkie victory.
Swarm of the Century: Everyone ignores Pinkie while she runs around collecting instruments. Pinkie saves the day.
A Friend In Deed: one of the few Pinkie-centric episodes, and she still doesn't really learn much. In the end, she was right all along.)
More first impressions:
Hey, Pinkie, you want to make clones of yourself? There can be nothing wrong with this plan. *nods sagely*
Not only does Pinkie Pie break the fourth wall, she is now acknowledged to break the laws of physics on a casual basis.
Now they're cloning themselves. Hooboy.
Apparently, the laws of physics don't apply to barns, either.

I predict a flurry of Batmare fics after this. And bad fics where they zapped the wrong Pinkie.
