Stephen Colbert’s “daily, week-long” web series “Lunch With Stephen” has aired its last and dramatic episode. “Thank God it’s TGIF Friday,” the host began. Wearing a winter jacket, Colbert is upset that his lunch buddy betrayed him by not skipping town with him. “I didn’t see you at the airport, friend,” he says menacingly while brandishing a pair of scissors. The rollercoaster week he’s had ends as wildly as it began, with Fish & Wildlife finally catching up with him.
