He must really have hated selling jewelry or its probably because they always mock him for that, but when he scratches his nose after they mock him, he unconciously flips them off.
Every time they repeat you sold perfume and jewelry he flips them off unconciously by placing his middle finger on his nose and leaning down.. like pretending to scratch it. He must really have hater doing that, or he is really pissed off because everyone keeps on mocking him for that. His movies are really good otherwise, except that one with Jet Li a few years back.
Check his other interviews for what I'm about to say: whenever an interviewer makes a reference to his hustling career as a perfume & jewelry streets-salesman, he gives them the middle finger :) here as well @ 1:43... Luv this guy, obviously not in a gay way:))
