Coco Tuesday

Aha! On a Tuesday, no less. I know you're impressed.
He's been full of gems lately. As you may have guessed, we call him Coco. In his previous school there was a kid who pronounced his name "Cornrad" and we reminded Coco of this, recently.
To which he replied: "I'm not a piece of corn. I'm a piece of hot chocolate!"
I think this is only second place to his comment on the history of our neighborhood.
On the way to school he complained about the incline. Well, I think he said hill, but I'm sure incline just slipped his mind at the moment. I think his question was:

"Daddy, why did they build these big hills?"
And I said, "The hills were already here,
all the stuff you see was just put on top.
Grass and trees would grow a fresh crop
if all the buildings were to disappear.
Long ago only greenery was to be found."
And he said, "You mean when the money people were around?"
I found this comment queer
so I had to stop
and let my jaw drop.
After some questions it became clear:
He meant the time of the people who adorn our bills.
