I have to say that "Lesson Zero" was certainly an interesting episode to watch. Twilight certainly showed that she is just as CRAZY as the other ponies of Ponyville...if not more so.
The couple of times where she said something like, "Or I'll be...TARDYYYYYYY!" Did you feel an urge to laugh listening to her yelling "tardy" like that? I know I did!
It was pretty cute watching the Cutie Mark Crusaders play with a beach ball. I think it proves that the CMC actually do take the time to just be kids, which I would hope makes them more likeable to some people out there. I have to agree that Twilight teleporting
inside the beach ball, popping it, and saying, "HI, GIRLS!" in that deranged-sounding voice was just creepy!

I was surprised the CMC didn't say something like, "Twilight! You broke/popped our beach ball!" Or, maybe, they didn't say that because it would have just come out wrong!
I got the impression that the writers were probably using this episode to tell everyone how thinking up Aesops to teach is getting harder and harder, and it's driving them
crazy!
