G: Look at this picture I drew of zombies rising from the grave.
Me: That's an awesome picture. I especially like the perspective you used here in the foreground. Now stop drawing and finish your math, or the zombies will come and get you.
G: Zombies don't care about math. They're already dead. They're undead.
Me: Oh no. Zombies care deeply about math. Didn't you know? Math and brains are the only two things that get zombies really excited. If they find out you've left some math undone, they'll come bursting in the door and stumble toward you, groaning "Maaaaath ... maaath ... expoooooonennnnts ..."
G: Good. They can do it for me when they get here.
