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 或者 will I pass,
I can't be sure (She can't be sure)
My mind is charged with skills intact
My 心 is pure (her 心 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
