陳永仁：你話三年。三年之後又三年，三年之後又三年！十年都嚟緊頭啦老細！
傻強：當一個人好唔專心咁做緊一樣野,而佢又望住你既話,佢就係警察
陳永仁：高音甜、中音準、低音勁。一句講哂，通透啦即係。
陳永仁：對唔住，我係差人！
劉健明：我以前無得揀，我而家想做好人。
黃志誠：因為我覺得你仲似番個人。
黃志誠：對不起，我沒有信心，我已經輸了。
黃志誠：世界唔應該係咁，做人唔應該係咁。
陳永仁：收嗲啦！呢句嘢我聽咗九千幾次啦！
韓琛：你以為派個臥底就能趕絕我啊！
受身無間者永遠不死，壽長乃無間地獄中之大劫。
往往都是事情改變人，人卻改變不了事情。
傻強：阿迪路，我知道點樣分邊啲喺差人！ 迪路：點呀？ 傻強：總之嗰個人做緊一樣嘢，但喺而好專心咁望住我哋，嗰個就係差人。 迪路：係喎...咁咪通街都差人？！ 傻強：好多嫁。
警察說他是警察他就是警察……
我只想當好人
出來跑 遲早要還 還是為自己多多著想吧
簡單嗎，殺警察你就能當壞人囉。
要是我當年沒有離開警校去做臥底，你有可能得到優秀獎嗎？
世界不應該是這樣 做人不應該是這樣
殺人放火金腰帶，修橋補路無屍骸
你們這些臥底真奇怪，都喜歡在天台見面…
我這個人特別堅強，我怕萬一妳催眠不了我，我可以自己催配合妳….
你那麼愛做事怎麼不去當警察………..
俾返個身分我！
我們都在不斷趕路忘記了出路 在失望中追求偶爾的滿足 我們都在夢中解脫清醒的苦 流浪在燈火闌珊處 去不到終點回到原點 享受那走不完的路
我以前沒得選擇，現在我想做一個好人。
好和壞 黑和白是對立的 黑社會和警察是不會做朋友的 古惑仔呢不見的是壞人 警察呢也不一定都是好人 有些人要相處一段時間你才知道他是什麼人
你說，你故意傷人已經好幾次了，我千方百計跟律政司說你心理有問題，要你去看心理醫生，可你還到處打人? 你是不是真的心理變態啊?你忘了自己是好人還是壞人啦?

Chan Wing Yan: Should I salute you? Lau Kin Ming: No, don't. How long have you been an undercover? Chan Wing Yan: I've followed Sam for 3 years; I had several other bosses before. All together, it's been 10 years Lau Kin Ming: 10 years? I should salute you, instead. Chan Wing Yan: I just want an identity. I want to be a normal man. Lau Kin Ming: Getting tired? Chan Wing Yan: You've never been a mole. You won't understand. Too bad I still can't find the stooge. I'll take him down if I've found him. Lau Kin Ming: Don't worry. Let me give you back your identity, I'll open your file, but I don't have the password. Chan Wing Yan: What's the Morse Code for undercover?
