Oh GAWD! If they choose smelly old drooling granny show Medium over wonderful, wonderful Chuck, I will BITE SOMEONE IN THE LEG! 

Commenter Nick C says he hears NBC is now narrowing down to a decision between Medium and Chuck, but I hope commenter David is right that it is merely a ploy to negotiate licensing fees down even further.
In the event the information is correct (and though I trust Nick did hear this, it still should be considered rumour) looking at both shows, if it’s one or the other I’d probably give a slight advantage to Medium.
