The teacher collected the permission slips, smiled, and began to chant.
Smoke filled the room, and a swirling portal opened in the middle of the blackboard.
The students rose up from their desks and flew through the door into the Shadow Zone.
Once the last student went through the portal, the smoke cleared.
The teacher sat back in his chair, put his feet on the desk, and enjoyed the silence.
The students would be back when the candle went out.
Candle?
Oh oh. He forgot to light the candle.
He pulled out his cell phone and called the union representative.
