In "Traveling Salesmen", Dwight and Jim, the two archenemies, have to go on a sales trip together... and absolutely nail it with some impressive teamwork. Jim does the talking, while Dwight asks if he can use the phone and calls to another paper company. After Jim is done, the prospective client tells them he rather stays with the big guys. Dwight asks him how important customer service is to him and points out that the other paper company he called, one of the big guys, is still having him wait. Jim grabs his phone, calles to Dunder Mifflin and immediately gets Kelly on the phone. Dwight proceeds to tell the client how dedicated he is, but the latter has already heard enough: they have a deal.
In "The Return", after Andy gets Dwight fired, Jim hides his phone in the ceiling and calls it during the day. This proves to be the trigger for Andy's total self-destruction in front of Michael and his wall-punch. Kick the Son of a Bitch indeed.
Dwight pepper spraying Roy in "The Negotiation" when the latter makes an attempt to attack Jim. Even better after one hears his talking head interview.
Dwight: Every day for 8 years, I have brought pepper spray into this office to protect myself and my fellow employees. And every day, for 8 years, people have laughed at me. Well, Who's Laughing Now?
It should be noted that while the text sounds badass, he's in tears from the cloud of mace he was exposed to himself.
An acceptable sacrifice in the face of danger.
In "Launch Party", Dwight manages to outsell the computer machine Ryan made to help with sells at the company. To note, Dwight made 1,270 sells, while the computer made only 1,208. And this was in one day.
Made even more awesome by Michael's announcement to Ryan in New York via webcam:
Michael: Hey, I just think you should know that one of my salesman beat your stupid computer. So take that, ass-fuck. (followed by Kelly slamming in Ryan's face on the screen)
In "Did I Stutter?", Michael is in denial that Stanley undermined him by refusing to listen to him during a meeting and being unapologetic about it, then when he orders everyone out of the room to talk to Stanley alone, he turns into a pathetic "Why don't you like me?" mess, which gives Stanley an opportunity to deliver a long-gestating The Reason You Suck speech about Michael's bumbling boss ways. But Michael is not a Bunny-Ears Lawyer without reason; just when that looks like that will break Michael, he instead takes the words to heart, sacks up, looks at Stanley, and firmly tells him Stanley while he respects his opinion, he cannot talk to his superior that way under any circumstances. Stanley respects the authoritative order and gives a half-hearted yet appreciated token effort to involve himself at the next meeting.
"Business Trip". Michael calls out his boss, David Wallac, via cell phone about he unfairly transferring Holly.
During Dwight's "fire drill" in "Stress Relief," Jim declares that he is not dying in the office and gets Toby and Andy to try to ram the door with the copier.
The entire fire drill scene is one awesome moment for Dwight, since the reason he did it was because everyone ignored his fire seminar from the day before.
In "Broke", The Michael Scott Paper Company (Michael, Pam, and Ryan) is out of money due to offering such low prices to undercut Dunder-Mifflin that turning a profit is impossible. However, their tactics have caused Dunder-Mifflin to lose customers to the MSPC, forcing David Wallace to offer a buyout as DM can't afford a money loss either. As the show goes to break before the final-act negotiation, Ryan and Pam beg Michael not to do his usual backfiring methods, which seems to suggest that Michael will indeed flub this as he flubs most meetings of this nature up to this point. However, Michael doesn't step wrong once in one of the best displays of Bunny-Ears Lawyer moments ever. While Wallace and Charles Miner try to lay out how bleak the MSPC's financial future is, Michael stands his ground and plays the same game, noting that it looks much worse for the duo if they lost what's left of DM to a fired manager and two meager salespeople. The result? Michael gets their jobs back, and in turn, Pam goes from receptionist to sales member. After Wallace finally concedes and leaves the room, all three of them are in disbelief that Michael pulled it off.
Michael (after David lays out that MSPC is in trouble): I'll see your situation and I'll raise you a situation. Your company is losing clients left and right. You have a stockholder meeting coming up and you're going to have to explain to them why your most profitable branch is bleeding. So they may be looking for a little change in the CFO. So I don't think I need to wait out Dunder Mifflin. I think I just have to wait out you.
When Michael is giving the above speech, Pam gives an Aside Glance to the camera and is beaming with pride. Michael can be extremely difficult, but he knows when to bring the awesome when everything is on the line.
Michael's response to being called a moron by one of his superiors in "Shareholder Meeting".
Michael: Uh... I'm not a moron. Time after time, my branch leads in sales. I have personally won over seventeen Dundy Awards, so I am not a moron. And I'm just trying to help, you know? So, you're the moron.
Even better was Michael outsmarting said superior's attempt to deny him the limo ride home, by rapidly gathering up everyone he came with and getting to their limo before the driver could get the message. They're the only ones with anything to celebrate, indeed.
In Season 7's "Counseling" episode, we finally see Toby's chops. For six seasons, he's been Michael's Butt Monkey; when Michael has to undergo six hours of counseling, Michael screws around for three hours. Then Toby gently turns the tables and gets Michael to talk to him. It doesn't last long, unfortunately, but it's brilliant to watch.
Michael gets a minor one at the end of "Andy's Play." Andy feels like he did an amateur job and Oscar decides to point out that it was an amateur play, but Michael angrily cuts him off and makes it clear that now is not the time for him to be a pretentious asshole. He then tells Andy that he was awesome, and that he can be sure he's being sincere because he has no filter, backing it up by pointing out that he booed someone. Not only does this show a lot of self-awareness on Michael's part, it also has him use complete honesty to make someone feel better.
Dwight finally gaining the upper hand on Jim. After spending nearly all day pranking each other (by hitting each other with snowballs) he creates an elaborate prank at the end of the day, by filling the parking lot with snowmen, and it's implied that Dwight is inside one of them, waiting to attack Jim with more snowballs. He's actually up on the roof, watching Jim destroy each and every snowman.
Andy's speech defending the rest of the office deemed "losers" by Robert California near the end of "The List".
Andy gets another one in "Lotto", when Darryl confronts him with his belief that he was unfairly passed over for the Regional Manager position and that he should have it over Andy. Andy swiftly dismantles his argument with a low-grade "The Reason You Suck" Speech pointing out that Darryl was not the shoo-in for the position that he thought he was. Doubles as a minor moment of heartwarming when you remember that Andy knew all of that because he went out of his way to ask about Darryl beforehand, most likely due to being concerned about that very thing himself.
Jim learns that Dwight is being set up as a scapegoat for Sabre to publicly fire. Not wanting to see his friend get humiliated, he tackles Dwight and fights him outside the conference room long enough for someone else to take the fall. Dwight even offers to buy Jim a drink in thanks.
In "Vandalism", Pam gets Frank back for messing with her mural by drawing things on his car (that would very easily be washed off with just water). Unfortunately, Frank is furious and begins to stomp towards her with clear intentions of harm. Cue Brian—one of the cameramen that we hardly ever see—running forward and striking him with the boom mic. Brian continues to wail on him, calling him out for intending to hit a woman.
Kevin giving Senator Lipton a well-deserved verbal ass-kicking for cheating on both Angela and Oscar and using them as pawns to further his political career. It is also heartwarming for proving that, although the accountants frequently have their disagreements, they really do care about each other.
The farewells in the same episode. The remaining cast talks about how they will miss the experience as they go their separate ways. It is heartwarming, funny and sad at the same time.
Dwight and Angela's wedding theme is "Sweet Child O' Mine".
Andy's speech to the Cornell graduates. He ends it with his infamous "sit here and cry" line. Instead of humiliating himself further, it gains him the admiration of everyone present. The same guy who acted like a total Man Child for most of the final season has developed a sense of humour about himself.
