In the seminal film Wild At Heart by David Lynch, which features a lot of violence and a lot of smoking and closeups of lighting matches, the male lead by Nick Cage gets a laugh by saying that he's been smoking ".... since I was about... four." But he is beat by this kid, who at two is obese and smoking 40 cigarettes a day! It's pretty sickening. But it's easy to see by his professional ease with handling the cigarette that this is not his first.
It'll be interesting to see how long he lives if he continues like that.
