This is Walter White speaking the line “I am the one who knocks” in a low, measured voice that tightens into a threat over about two seconds. It feels tense and menacing, with a darkly comic edge when it lands after a small boast, because the speaker suddenly sounds far more dangerous than expected. The line comes from Breaking Bad.
