#Breaking Good Companion for 1x04
Fun factoid: Creator Vince Gilligan got his start in television with the series The X-Files, which featured a character The Smoking Man (William B. Davis). The title of episode 1x04, “Cancer Man,” was also the disparaging nickname that Fox Mulder had given to the Cigarette-Smoking Man on that series. Bonus fact: Morley’s are a fictional brand of cigarette seen in many films and TV shows — they’ve been puffed on by such icons as Jack Bauer in 24, Spike in Buffy The Vampire Slayer and Chandler in Friends. But most famously, they are the poison of choice for Cigarette-Smoking Man. A Morley cig is glimpsed in Breaking Bad’s pilot, being flicked out of the RV window by thug Emilio.
