- Dae-su Oh: If they had told me it was going to be fifteen years, would it have been easier to endure?
- Woo-jin Lee: Your gravest mistake wasn't failing to find the answer. You can't find the right answer if you ask the wrong questions.
- Dae-su Oh: [on receiving three chopsticks with his prison rations] All I could think about in that moment was the guy in the next room was eating with only one chopstick.
- Dae-su Oh: Who the hell are you?
- Woo-jin Lee: Me? I'm a sort of scholar. And my major is you. A scholar studying Dae-su Oh; an expert on Dae-su Oh.
- Woo-jin Lee: Your tongue got my sister pregnant! It wasn't Woo-jin Lee's dick; it was Dae-su Oh's tongue!
- Dae-su Oh: [after getting knocked over and taking a drag of a cigarette] "Dick-shit"... a new word. Television doesn't teach you swear words.
- Dae-su Oh: If by any chance Mido should find out the truth, you son of a bitch, I'm going to rip you limb from limb. And your remains will never be found. Why? Because I'm going to swallow every last bit.
- Woo-jin Lee: You want to torture me, but I can simply kill myself first. Do you want revenge, or do you want the truth?
- Mr. Park: You see, they say that people shrivel up because they have an imagination. So, don't imagine anything, you'll become brave as hell.
- Dae-su Oh: If you stand aimlessly at a phone booth on a rainy day, and meet a man whose face is covered by a violet umbrella, I'd suggest that you get close to the TV.
- Dae-su Oh: [Dae-su is about to use a clawhammer to yank out someone's teeth] Each one I yank out will make you age for one year. Ready to talk?
- Woo-jin Lee: You really are the very monster I created, aren't you? But you won't find out the "why" of this if you kill me. Fifteen years of being curious would go to waste.
- Dae-su Oh: [Dae Su is on his knees. Begging] Please. Don't tell Mido. What has she done wrong? You know it was all my fault... I have committed an unforgivable sin, against your sister. And I also... Did you wrong. Please leave Mido alone... If by any chance Mido finds out the truth, you son of a bitch, I'll tear you limb from limb. And your remains will never be found. Why? Because I'm going to swallow every last bit.
- [Crawls over to Woo-Jin and starts to grovel to Woo-Jin]
- Dae-su Oh: Woo-Jin! Please, sir, I made a mistake. Please forget what I said. Sir, Woo-Jin!
- [Raises up on his knees to face Woo-Jin]
- Dae-su Oh: We're Evergreen Oldboys, remember?
- [singing]
- Dae-su Oh: With the energy of a green pine tree/The Great Sangnok High...
- [Grabbing hold of Woo-Jin's leg. Begging, and weeping]
- Dae-su Oh: I'll do whatever you want. I'll do anything, I beg you. Woo-Jin, if you want me to be your dog. I will. From this moment on, I am Woo-Jin's dog. I'm your bitch.
- [Starts barking maniacally like a dog]
- Dae-su Oh: Look, I'm wagging my tail. I'm a dog, I'll guard your house. I'll be your slave...
- [Starts crying frantically, and falls to Woo-Jin's feet. He begins to lick his shoes... Humiliated... defeated...]
- Dae-su Oh: Erasing my memory and telling me to find the truth was cowardly. I won. So die like you promised.
- Woo-jin Lee: I'm going to kill every woman you love until you die. You're notorious for not protecting your women.
- Dae-su Oh: When the melody turns on, gas comes out. When the gas comes out, I fall asleep. I found out later it's the same Valium gas the Russians used on those Chechen terrorists.
- Woo-jin Lee: Mister. Are you alright? What happened to you? Saewoon Apartments, Eung-am building 8. Take care of him.
- Dae-su Oh: Thank You.
- Woo-jin Lee: Not at all. Well, then. Farewell, Oh Dae Su.
- Dae-su Oh: Farewell, Oh Dae Su.
- Mr. Park: [hands Dae-Su a business card while grinning a big gold-toothed grin] This dentist is really good.
- Dae-su Oh: Please. Don't tell Mido. What has she done wrong? You know it was all my fault... I have committed an unforgivable sin, against your sister. And I also... Did you wrong. But, please leave Mido alone... If by any chance Mido finds out the truth, you son of a bitch, I'll tear you limb from limb. And your remains will never be found. Why? Because I'm going to swallow every last bit.
