So it turns out the finale took place during Lisa's girlfriend's birthday, and Lisa wanted to win so she could buy the girlfriend something nice with the hundred-thou. And it turns out Dan Barber has a personality and is adorable, and Richard is funny and geeky about Star Wars (shocker, that). So why didn't we get to see all of this stuff during the regular broadcast? For one thing, it might have livened up a rather pro forma finale. We rather suspect we didn't see it because, by humanizing Lisa and showing Richard as less of a victim, it detracted from the predetermined narrative arc.
