- He Zhiwu, Cop 223: If memories could be canned, would they also have expiry dates? If so, I hope they last for centuries.
- Woman in blonde wig: Actually, really knowing someone doesn't mean anything. People change. A person may like pineapple today and something else tomorrow.
- He Zhiwu, Cop 223: We're all unlucky in love sometimes. When I am, I go jogging. The body loses water when you jog, so you have none left for tears.
- Cop663: Since she left, everything in the flat is sad. Everything needed lulling to sleep.
- [to a bar of soap]
- Cop663: You've lost a lot of weight, you know. You used to be so chubby. Have more confidence in yourself.
- [to a threadbare wet dishcloth]
- Cop663: You have to stop crying, you know. Where's your strength and absorbency? You're so shabby these days.
- He Zhiwu, Cop 223: We broke up on April's fools day, so I took it as a joke. I'm willing to humor her for a month.
- Woman in blonde wig: Somehow I've become very cautious. When I put on a raincoat, I put on sunglasses too. Who knows when it will rain, or when it will turn out sunny?
- [663 finds his apartment is flooded]
- Cop663: Did I leave the tap running, or is the apartment getting more tearful? I always thought it would cope okay. Didn't expect it to cry so much. When people cry, they can dry their eyes with tissues. But when an apartment cries, it takes a lot to mop it up.
- Cop663: [to new bar of soap] You mustn't let yourself go. You've gained weight so fast. She may have gone but life goes on. You must stop indulging yourself.
- Cop663: [to new towel] You're a real disappointment to me. You've changed so much. You can't just switch personality like this. Her walking out is no excuse.
- Cop663: [as it drips] It was such a relief when I saw it crying. It may look different, but it's still true to itself. It's still an emotionally charged towel.
- He Zhiwu, Cop 223: At the high point of our intimacy, we were just 0.01 cm from each other. I knew nothing about her. Six hours later, she fell in love with another man.
- He Zhiwu, Cop 223: We split up on April Fool's Day. So I decided to let the joke run for a month. Every day I buy a can of pineapple with a sell-by date of May 1. May loves pineapple, and May 1 is my birthday. If May hasn't changed her mind by the time I've bought thirty cans, then our love will also expire.
- He Zhiwu, Cop 223: Any canned pineapple that expires on May 1?
- Cashier: You know what day it is today?
- He Zhiwu, Cop 223: April 30?
- Cashier: Right. You think we sell outdated stock?
- He Zhiwu, Cop 223: There's still two hours to go.
- Cashier: Nobody would buy it. Get a fresh one.
- He Zhiwu, Cop 223: People like you are hung up on freshness. You realize what goes into a can of pineapple? The fruit must be grown, harvested, sliced, and you just throw it away! How do you think the can feels about that?
- Cashier: Buddy, I only work here. Who cares about how the cans feel? What about how I feel? Loading, more loading, unloading... How I wish cans wouldn't expire! It'd save me loads of work. You like expired cans? Help yourself! As many as you like! On the house!
- [Faye is confronted by her boss]
- Faye: I'm not daydreaming.
- Manager of 'Midnight Express: Right. You're not daydreaming. You're sleepwalking.
- [633 after Faye fails to meet him at the California restaurant in Hong Kong]
- Cop663: Actually, she did go to California that evening. But it was the other one.
- Cop663: I thought we'd stay together for the long haul, flying like a jumbo jet on a full tank. But we changed course.
- [223 phones some potential dates]
- He Zhiwu, Cop 223: Lulu? This is Qiwu. Want to come out for a drink? You're in bed already? This early? You were asleep? Never mind. Bye.
- [He phones another]
- He Zhiwu, Cop 223: Chieko-san? Guess who? This is Qiwu. That's right. Want to come out for a drink? Your husband? When did you get married? Five years! Has it been that long? You have two kids! You're happy, that's great! Okay, never mind.
- [He phones another]
- He Zhiwu, Cop 223: Is Kong Siu-wai there? This is He Qiwu. We were classmates in grade four. You don't remember? Nothing, goodbye.
- [633 on the previous owner of his restaurant]
- Cop663: He has great business sense. First he sold me fish and chips, then the whole thing.
- [223 leaves the store]
- He Zhiwu, Cop 223: [voice-over] Somehow everything comes with an expiry date. Swordfish expires. Meat sauce expires. Even cling-film expires. Is there anything in the world which doesn't?
- [to a passing street person]
- He Zhiwu, Cop 223: Buddy, how about some swordfish?
- Street person: [223 gives a can of swordfish to the passing street person. The street person looks at the can and throws it on the ground]
- Street person: It's expired. Don't want it.
- He Zhiwu, Cop 223: You sure?
