Numb3rs Season 4 Episode 10

In the scene where David is talking while sitting on the floor on the corner of the elevator, one can see that there's a missing wall on the elevator, through which the scene is being shot. A few seconds earlier, it's possible to see this wall from another angle, when the set was arranged differently.

The usually articulate Charlie mixes his metaphors, blending John Searle's "Chinese Room" argument against computer intelligence into Alan Turing's famous "Turing Test" - and coming up with a stunted analogy that is only vaguely related to anything in the episode.

The "Chinese Room" thought experiment is one of John Searle's most famous arguments for why a computer can never have a "mind." The man in the room is an analogy for a computer, blindly processing Chinese symbols he doesn't understand, while anyone outside the room is convinced he must be a native Chinese speaker, based on his responses to their questions - in Chinese. Charlie mixes this up with the "Turing Test" - which is similar, but not really the same thing. In the Turing Test, someone is connected remotely to both a computer and a real person by teletype and must determine which is which.
