* Matt and Ronnie are trying to find the office of a business. They find a forwarding house, and talk to the clerk there.
--> Matt: "You sit here all day, forwarding letters?"
--> Clerk: "All day... every day... We're not allowed a computer, because that would be too distracting... and that camera monitors me... all day... every day..."
--> Ronnie: "You enjoy your job?"
* "It's finally happened. You've become Elliot Ness."
* Just about any scene of Matt and Ronnie nattering at each other. For example, from the very first episode, as Matt tries to question a witness who only speaks French:
--> Matt: (stumbling) Avez vous. . .(turns to Ronnie) What's "seen"?
--> Ronnie: {Proceeds to speak to the man in perfect French)
--> Matt: You speak French?
--> Ronnie: What do you think I am, some sort of Neanderthal?
--> Matt: You might have said something before I made a tit of myself.
--> Ronnie: Where's the fun in that?
** (this scene is made all the funnier by the fact that JamieBamber is fluent in French and probably could have spoken the language for the entire ''episode'', never mind the scene)
* When Alesha informs James and George of an defense attorney's intent to present a ludicrous (but still plausible) defense:
--> George: "Let's not panic. No sane judge would let that get beyond a hearing. So who did we draw?"
--> Alesha: "Judge [=DeMarco=]."
--> (James winces and groans)
--> George: "Oh, God. Let's panic."
* Matt and Ronnie are talking to several gang members to discern if they're responsible for the death of a young boy. Matt bets that if he makes a basketball shot, the gang leader will answer his questions. So Matt takes the ball, makes the play. . .and misses by a mile. The boys laugh their heads off at him, but the gang leader decides to answer Matt's questions anyway, as a "thank you" for amusing him.
* The special features on the Season 2 DVD include a 10-minute gag-reel. Most of the clips are typical, such as flubbing lines, malfunctioning props, etc. But the highlight is a botched scene where Matt and Ronnie are interviewing a witness. Distracted by the loud music playing in the background, Jamie Bamber begins struggling not to laugh before finally cracking up, declaring, "I'm sorry; I can't fucking do this". Knowing that the take is no good anyway, Bradley Walsh begins dancing to the music. What makes this double as a CrowningMomentOfAwesome is that he continues to say his lines with a straight face as though this is perfectly normal, even as his movements get increasingly goofy, pretending to be unaware as to why Bamber and the other actors are laughing so hard that they're doubling over.
* In the episode "Sacrifice", a doctor the detectives have been speaking with gives Ronnie her card, ostensibly in case they need more information. The GenreSavvy Matt sees through her ruse and as they walk away, starts gushing like a teenage girl, "She just gave you her phone number!". An amused Ronnie merely replies, " I know".
* In "The Wrong Man", the detectives are alerted to a case of medical malpractice by an anonymous informant. The investigation soon stalls.
--> '''Ronnie''': We need to schedule a rendezvous with "Deep Throat"
--> (Matt's eyes widen and he starts purring like a cat)
--> ''''Ronnie'''(snaps): Not the porn film!
