Make him smiling

I was helping Reilly, my first grader, build a Space Alien from items around the house; a school assignment due tomorrow. As a final touch we were gluing a rubber band to his head to form a mouth.

"Make him smiling."

"Why?"

"Because he's happy."

"Why is he happy?"

"Because he just finished sucking someones brains out of their head."

"You and I are so ending up in the school counselor's office."
