[Mac storms out of his disciplinary hearing]
Det. Don Flack: Did you just walk out?
Det. Mac Taylor: Apparently I'm the kind of person who just does whatever he wants, why disappoint them?
Det. Mac Taylor: Do you remember your first collar?
Detective Stella Bonasera: Oh, yeah.
Detective Stella Bonasera: A shoplifter on 43rd and Eigth Avenue. This guy took one of those "I Love New York" t-shirts from the souvenir shop. It was the proudest moment in my life.
Detective Stella Bonasera: Two days later, I arrested him again in the same store.
