Ms. Bitters in “Door to Door”

[In the classroom a student is held in mid air by a harness and is stacking cards in a tower]

Now, add the dead weight of students like you.

[The child adds a huge stack of cards to the tower. It sways dangerously]

So you can see, children, that our whole society is nothing more than a perilous house of cards...

[The tower collapses into a heap]

...destined to collapse under its own weight!
