"Sneakerhead" was juvenile, at best. The diplomat and rapper were AWFUL. Both actors over-emoted instead of delivering solid performances and ultimately were just clown caricatures. Even if it was for comedic relief, it was an insult to the audience's intelligence. What made this a great episode for me was that all of the performances by the regular cast against the subplots that revealed more of their individual characters, how they interact, and how they have grown. If the writers could just present more episodes like this but with intriguing storylines and better written antagonists, Numb3rs would be a better show.
