Speaking of BBQ - if you're hanging/waiting for the charcoals to light - catch Tony Scott's use of facial hair on Numb3rs. "Trust Metric" KCAL 9 Saturday 6:00pm. For this episode, Tony had Peter McNicol's character grow a beard. In fact, he asked many cast members to grow beards and/or get different haircuts. Tony explained at a production meeting, "Because I have none, I am fascinated by everyone else's hair."
