He’ll get and invisible grade- 0.

I see a face in the curls of blue-dress girl!

And, here is your invisible mark!

Make yourself invisible in this classroom, go see the principal

Will he get an ‘INK’ for his grade?

… Just put my paper up to a candle or an incandescent light bulb and you can see what my answers are.

In other words Miss Smiggledorf, I didn’t study and just punted….

So that no one else can copy your grade either, I give you an invisible F…

Disappears to be a rather lame excuse.

Unlike some challenges a teacher might face, this one is too easy. No readable answers = they all get marked wrong = the kid gets a 0.

That’ll be the last time he tries that stunt.
