Now we're almost to the house. Let's walk up the stairs and knock on the door.
We must knock in a special way, or the door won't open. We must knock using three sets of sixes.....
...... yes. 666.
Let's try it.......
*knock* *knock* *knock* *knock* *knock* *knock*
*knock* *knock* *knock* *knock* *knock* *knock*
*knock* *knock* *knock* *knock* *knock* *knock*
