Where does he get this stuff?

Today Dad picked Blake up from school, and Blake was carrying this box. It says "To Blake from Grandma & Grandpa". Jon couldn't figure out how in the world Grandma and Grandpa brought a box to Blake's classroom, and what in the world was in it?

So as soon as they got home, Blake opened his box. Guess what was in it?

His backpack!

What??!!!

Apparently, Blake found a box at school, asked his teacher if he could have it, wrote his message on it, and put his "surprise" in it. I don't know if he's hinting something to Grandma and Grandpa or what, but this must be a Cusack thing because I never, in my wildest dreams, would've thought of doing something like this.

And people wonder why we only have one child ...
