This is from Spike and Twilight's duet which can be found here: link

I was prepared to do my best
Thought I could handle any test
For I can do so many tricks
But I wasn't prepared for this
Levitation would have been a breeze
Facts and figures I recite with ease
(Twily: The square root of 546 is 23.36664289109
Math Pony: She is correct!)
I know all about friendship's bliss
But I wasn't prepared for this

Will I fail o will I pass,
I can't be sure (She can't be sure)
My mind is charged with skills intact
My corazón is pure (her corazón is pure)

Oh, I've taken my share of licks
I've made it through the thin and thick
But no, I wasn't (no she wasn't)
Oh no I wasn't (oh no she wasn't)
No I wasn't prepared for this

1, 2, 3
1, 2, 3

I don't wanna change you
I don't wanna make tu different
I'm happy with the way it is
And the way it isn't

We fit like puzzle pieces
In a perfect way
Don't go seein' raindrops
On a sunny day

Oh, i don't believe
that my world isn't real
And i wouldn't take tu from yours
I just wanna find me some magic somehow
Oh, don't be a neighsayer now

I wish tu saw yourself
The way i've always seen you
You're so much stronger now
For all you've been through

I don't believe
that my world isn't real
And i wouldn't take tu from yours
I just wanna find me some magic somehow
Oh, don't be a neighsayer now

Together
Is better
You're my best friend forever
Together
Whatever
May come my way, i say

That i don't believe
that my world isn't real
And i wouldn't take tu from yours
I just wanna find me some magic somehow
Oh, don't be a neighsayer now
