My all time favorite quote, or exchange of quotes is:
“Who am I?” [pause, pause] “Who AM I?”
“Heisenberg” [sheepishly whispered]
“You’re goddam right!”
Leave the Gun take the Canoli’s ?
Luke... I am your Father ?
Or, from the same series:
“Who do you think you’re talking to?”
[Silence]
“I am the danger. I am the one who knocks.”
