- Grissom owning the lawyer's ass in the episode "The Accused is Entitled". A famous movie star has been accused of murdering a girl. He's hired a pretty ruthless lawyer and also Grissom's mentor to decimate the evidence the CSIs have collected during the prelim. Because Grissom was losing his hearing at the time, he's not collected any evidence in the high profile case and throughout the hearing, the mentor and lawyer have destroyed every piece of evidence the prosecution has as well as call into question the skills and even character of the CSI team and it looks like the judge will throw the case out even though the accused is guilty. Grissom then decides to take the stand with some evidence he's found so his mentor advised the defense lawyer to "speak softly" so that Grissom will have trouble hearing her. However, Grissom can lip read and after a few times asking her to repeat herself, Grissom answers and provides his evidence flawlessly. Boom! Grissomed!
- The ending sequence of "Blood Lust" is amazing piece of work all around. Greg has proved that six people of twelve in a mob beating incident were involved by finding their DNA on the victim, but the other six cannot be forensically linked to the crime though they've bragged about it. Grissom sits in Brass's office and tells him the bad news, lamenting that physical evidence is limited by human action. After a brief discussion, Grissom tells Brass this is as far as he and his team can take it. The scene cuts to Brass interrogating one of the six, telling him that no, he's not a hero, the cabbie wasn't at fault in the accident, he wasn't trying to flee the scene, he was reaching for his radio to call for help, and the guy's on the hook for first degree murder. His lawyer asks if the DA is willing to deal, and Brass says the price is naming the others in the mob. Meanwhile, through the whole interrogation room scene, Radiohead's "Everything In Its Right Place" has been swelling slowly in the background, and as it pulls out through and pans away from the window to the interrogation room to Grissom, the title line of the song plays and Grissom starts to smile. It's an excellent moment in pretty much every way; showing the success of the individual characters, the success of the characters as a team, acknowledging that the whole team was needed for the win, and even the behind-the-camera cinematography and sound guys nail their parts.
- The glorious Kansas City Shuffle by the villains in the episode "Suckers". There's a murder (fake), to cover a robbery (also fake), to cover an art forgery (fake again), to distract from a casino heist (quasi-fake)... all leading up to an insurance scam by the promoter of the art exhibit — and he admits it to Grissom's FACE at the end of the episode. Crime has never looked so diabolically cool — and not a single murder to be seen. The fact that the entire episode had backup music by Gilbert and Sullivan is just gravy at this point. Grissom admits that he cannot prove the insurance scam in a court of law. He will, however, just turn everything over to the insurance company, and let them handle it.
- In "Swap Meet," after a statutory-rapist claims to know the identity of the killer and requests a deal:Brass: Too late.
- Sara can be a polarizing character, but there's no denying that she got one of these in an early episode. The scene is in the interrogation room, where it looks like they're unfortunately going to have to let the rapist/killer go due to Not Proven. Suddenly, in comes Sara with some new evidence: the missing stewardess's suitcase, which went missing with her and which the team had been trying to find through most of the episode. The suspect is incensed; how dare she go through his car without a warrant! Sara unzips the suitcase, and... there's a tape recorder in there. Turns out it wasn't the stewardess's suitcase after all but an identical one, and she just tricked the guy into confessing where he was hiding the real one and got it all caught on tape!
- The forensic tour-de-force following Nick's abduction and live burial, in which each and every major character got to contribute some crucial observation or Chekhov's Skill to engineer his successful rescue, was a collective example.
- When Greg Sanders is interrogated at an inquest to determine his culpability in running over a proven murderer, he was accused by a judge of drinking prior to the event. After a second of panic, Greg proceeded to, calmly and systematically, prove exactly why the very little alcohol he consumed many hours earlier had no effect on him, performing a multitude of calculations in his head as he explained them to the jury. The judge was thoroughly humiliated. Just to give some clarity, it takes Greg almost 10 seconds to work out the calculations necessary to prove that the alcohol wasn't a factor. Further, the calculations themselves are fairly difficult to do without notes or written calculus. End result: Sanders 2, Judge 0.
- The event that led to Greg's inquest in the first place: After a bit of Car Fu to stop a gang member from beating a tourist, Greg took a severe beating from the rest of the gang, fighting, scratching and getting spat on the whole time. He stayed conscious long enough to give the team a detailed description of the gang, and to tell them he had DNA evidence under his fingernails. The guy Greg saved got a moment of awesome too. When Greg is being harassed by reporters over the events, the man comes to his rescue and says Greg saved his life and the reporters should be ashamed for trying to make him feel guilty for running over the attackers. The guy in question being Bobby Singer also helps.
- The episode "Living Legend" involves the discovery of what seem to be the remains of mysteriously vanished crime lord Mickey Dunn, and includes a bevy of awesome moments:
- Doc Robbins gets the first, and it's generally agreed to be his single best moment in the history of the show. He walks into the morgue to find a presumed journalist taking photos of the "famous" skeleton on his table. Robbins demands the camera. The guy pretends to offer it but is clearly thinking "Old man with a stick, no problem", and he tries to force his way past. Approximately ten seconds later, he's groaning on the floor and Robbins is calling for security.
- Honestly, the original Mickey Dunn (played by Roger Daltrey no less), for his entire elaborate scheme of string murders while having everyone think he's dead. He appeared in disguise on the news and they still didn't recognize him.
- Catherine (who had a crush on Mickey as a teenager) totally steals his thunder in the episode's final scene and blows his attempted Thanatos Gambit to itty-bitty bits: Mickey had been shot years before, and although he survived, the bullet was slowly migrating to his heart; he decided to kill the people who set him up to die when it was just about to hit, reasoning that even if he got caught, he'd die before he did serious time and that with this final act, he would become a legend forever. Sure enough, he has a heart attack in interrogation and thinks he's won... only to wake up in a hospital room with Catherine by his bedside, as she calmly explains that because "mob doctors become mob doctors because they SUCK", the hospital surgeons were able to save him easily, and he's going to prison for the rest of his life. A prison full of criminals who had never heard of him, meaning his "legend" will slowly die.
- Hodges "lucky day," the one day in which absolutely nothing goes wrong for him, ever. Not only does he attract the attention of a beautiful woman, win the online auction he was bidding on, and get extra potato chips when the machine triple dropped, but he managed to crack a case that had stymied Grissom and the rest of the CSIs. And he managed to make it look effortless.
- Nate Haskell, the serial killer obsessed with Ray Langston (on trial for stabbing said Ray), has managed to get a neurologist to say that Haskell isn't responsible for any of his criminal actions, due to brain damage that is theoretically caused by a specific "warrior gene" anomaly present in Haskell's genome. Ray takes the stand, and during the cross examination (undertaken by Haskell as part of his plan), Ray says that there's no evidence that the gene causes people to become serial killers. When Haskell asks what experience Ray has that allows him to make such a statement, Ray simply and calmly lays out that he has the gene, and has lived his life trying to help people, not hurt them, blowing the defense right out of the water.Ray: You know, a good lawyer never asks a question that he doesn't have the answer to.
- Ray Langston at the crime scene (a prison) in "The List":Ray: Listen up! I want your sneakers! I want your jumps, I want your DNA! I wanna see your hands, I wanna see your eyes! THIS MAN YOU KILLED WAS A COP, SO THERE WILL BE CONSEQUENCES! PRISON WILL NOT PROTECT YOU! (cut to opening credits)
- Doc Robbins saving the baby in "Unleashed". They have stumbled on the scene of a teenage girl's suicide after a passerby stops their car on the way home from breakfast. Robbins stays with the body while Nick heads back to the car to fetch his kit, but Robbins quickly calls Nick back when he realizes that the dead girl was pregnant, almost to term and the fetus is still moving. Using Nick's pocket knife and help, Robbins quickly does a c-section, pulls the baby out and then gives her mouth-to-mouth until she starts breathing and crying. At the end of this storyline, it turns out the girl was Driven to Suicide after a harassment campaign from an Alpha Bitch. Nick and Ecklie with a bunch of unnamed officers come in the school and drag the girls out in cuffs. Right before they do, the principal tries to stop them by saying "none of these girls are bad kids" and Ecklie and Nick just tell her off.
- "Malice in Wonderland": Hodges and his mother are being held hostage, restrained and at gun-point, in an ambulance on its way out to the desert, where they'll be left to die. Fed up with his mother's over-idolizing views of him, he goes into a bout of Heroic Self-Deprecation...that ends with him stating that one of the few things he has is "knowledge of the physical limitations of duct tape", at which point he breaks his restraints, disables the person holding the gun with a syringe, and takes the gun, leaving the other crook having to resort to accelerating to the point that shooting him would get them all killed just to keep from being completely owned by the lab rat. Yes, you read that right; Hodges.
- In "Passed Pawns", we see Brass lose his temper at a new would-be mob boss after finding out he has a young man captive and under interrogation for the location of drugs that his mother has already sold. When the Smug Snake gets short and demands that Brass treat him with some respect after he demands the captive be let go, gesturing to his bodyguards to muscle in, Brass loses patience and has drawn his gun, shot the leg out of one of them, and aimed at the now nervous boss in a second, threatening to go down shooting him. Needless to say, the hostage is rescued.
- "Keep Calm and Carry On" had an awesome ending. A woman is found murdered after she got off of a plane and the main suspect is her extremely abusive husband. After it turns out it was someone else, Nick confronts the husband, who's gloating about how her death was "cheaper than divorce". Right then and there, Nick has him arrested for shoving and threatening Doc Robbins earlier in the episode. The man tries to point out that it can easily removed in court but Nick points out that it won't go through until Monday, meaning he's gonna stay in jail for a weekend at least.
- Lady Heather absolutely destroying her Stalker with a Crush in the Grand Finale, without even looking at him. Pity she didn't notice he'd already swiped the MacGuffin.
Awesome / CSI
