Here's a look at tonight's sci-fi TV:
Chuck, 'Chuck Versus the Tooth' - Turns out having a supercomputer downloaded into his brain wasn't exactly the healthiest thing for Chuck. Who knew? The big bad Nerd Herder is ordered to see a CIA psychiatrist (guest star Christopher Lloyd) after having disturbing nightmares. Can our boy go toe-to-toe with Doc Brown to save his spy career? Elsewhere, Anna (Julia Ling) heads back to the Buy More hoping to rekindle her relationship with Morgan. I guess that Benihana Chef couldn't compete with Morgan's, er, unique charm.
