Dear Princess Celestia,
This week I didn't learn anything about friendship, but that's o.k because I don't need to, everypony is my friend.
If in the event I find somepony who isn't my friend, I will harass and stalk them until they give in and become my friend!
Unless they're a big hairy spider.
Frak the spiders.
Spiders can die.
Your bestest bestest best friend,
Now there must be a mathematical way to determine the percentage chance of Yankee Doodle Donkey finding Waltzing Matilda in Ponyville (which probably only has two damn donkeys anyway) without Pinkie Pie's help before her other helping drives him to move, which he isn't even ever intending to do again. Sooooo.... yeah.
I think despite (and perhaps even because of) it's giant plot hole and absolutely terrible message about friendship, that just be one of my favourite episodes.
Or maybe just because of how cool that song was.
