The Big O/Fridge

Fridge Brilliance

 * When Alex Rosewater tries to start up Big Fau, Big Fau goes through the whole "Cast in the name of God" stuff before going into "Ye Not" before shutting down. It's not the fact that Big Fau shuts down automatically due to missing components, but is actively rejecting Alex with the "Ye Not."
 * Not to mention there is historical precedent. An executioner's weapon would be blessed by a priest, so when it was used, the executioner's role was ordained by God, and thus, not a murderer, hence "Ye Not Guilty."
 * Roger's Catch Phrases "It's Show Time" and "Action" make a lot more sense at the end of the series.
 * In episode 11, when the sax player and his blind girlfriend are eating, there's no food on his plate, but he makes motions and noises with his utensils as though he's eating. At first I thought this was an oversight by the animators, but then I realized: they're dirt-poor; he's secretly giving her his food.
 * The Big archetype is extremely fast and flexible but the Bigs themselves aren't. I can't think why it would be so flexible but the speed makes sense since while Bigs are slow but they have heavy weaponry and armor to slow them down.

Fridge Logic

 * The first time Roger meets Seabach, the later announces his name is "Schwarzwald." Roger looks up and says, "black forest?" which is what that means in German. So... there are foreign languages in a city where they're unsure if outsiders exist? And, it only gets worse when Dan Datsun identifies Michael Seabach of being if German descent, which means on some subliminal level foreigners make sense even though officially no one is sure.
 * Not to mention that Datsun, and seemingly everyone else, don't recognize a single word of French.
 * Why would they recognize French? They might have never seen the words before
