And just for the record...

...I think that from now on I'm going to use Jackson's quiz answer to explain Point of View to my future students:

An omniscient 3rd person is like God. He knows everything. He knows what Jane is thinking and that Jack needs to poop. A limited 3rd person is restricted to knowing about one character. He knows what Jane is thinking, but not that Jack needs to poop.

Thanks, Bryce, for your "pooping up the mower" line, which started all this.
