In math class, someone was writing down a poem:
Sir, I bear a rhyme excelling
In mystic force and magic spelling
Celestial sprites elucidate
All my own striving can't relate
Then, of course...
What am I?
Later that day, the kid asked if anyone knew. No one did.
The kid didn't know either, and we were stuck thinking about it.
That night, I had a moment of "wow!". I told everyone, and they said it was genius.
So, what is it?
