* Donna getting Louis to panic and run away from trying to get his reward from Harvey for doing Harvey a favor.
-->Donna: (fake crying)
-->Louis: Oh shit... (runs away)
** Also, Harvey's realization that Donna used the same trick on him before to get him to let her parents stay in his condo
** A CallBack moment occurs when Donna begins crying in front of Mike as evidence of her excellent acting skills. Mike, of course, panicked too.
* Mike borrows Harvey's corporate credit card for use in a case:
-->'''Harvey''': If this comes back to me smelling like stripper, you're fired.
* Harvey telling Mike he's getting really good at ... ruining the moment.
* Mike commenting that he was a fabulous criminal, only for Harvey to remind him about how his briefcase fell open and then there was weed all over the floor.
* Any time Jessica brings the snark:
-->''The really important thing is - that I'm taller than you.''
-->''And when you're running the firm of Litt, Nothing, and Nobody...''
-->'''Harvey''': You could teach-
-->'''Jessica''': I could also kill myself.
* Every time Mike gives Harvey an idea, only for him to reject it. A few scenes later, Harvey inevitably does the exact same thing Mike told him to do, insisting that he did ''not'' say it was a bad idea.
* For some unknown reason, Harvey has Michael Jordan's phone number. Mike calls his bluff, dials the number, and promptly ''freaks out'' as the call actually connects.
** FridgeBrilliance when you remember that Harvey keeps various signed sports memorabilia in his office among which are basketballs.
** Turns out MJ is a client of Harvey's.
* Louis's HiddenDepths? Going to the shooting range when he wants to be alone. Harvey decides to quote ''Film/DirtyHarry'' to him:
-->''A .44 Magnum? You feelin' lucky today, punk?''
* Apparently Harvey's pre-trial ritual involves Donna, at least five minutes, [[NoodleImplements and a can opener]].
** and, somehow, thumbtacks
* Louis's reaction to the tickets to the American Ballet Theatre that Donna bribes him with. His eyes look like friggin' ''saucers''.
** And then when he turns them down and Donna reveals Jessica already knows about his sandbagging the DNA test:
--->'''Louis''': Oh, that phony bitch.
* Mike's dinner with Jessica at the beginning of Season 2:
-->'''Mike''': You look so young!
-->'''Jessica''': Well you know what they say...
-->'''Mike''': Black don't crack!
-->'''Jessica''': (simultaneously) True beauty is ageless.
-->'''Mike''': ... That's what I meant to say.
* Mike's grandmother reveals that one of her stories she told Mike was actually fake. As he's leaving, he jokingly asks her if there's any other secrets she hasn't told him such as if he's really from Krypton. She simply nods slowly and says "Possible..." with the straightest possible face.
* Harvey and Jessica make the same joke about redundant departments to Louis. Louis naturally has completely different reactions to the two of them.
* This exchange between Harvey and Jessica:
-->'''Harvey:''' There can only be one.
-->'''Jessica:''' We're at a funeral and you're quoting Highlander?
-->'''Harvey:''' Yeah, a lot of people die in it. Seems appropriate.
* When the firm ends up being threatened with having their rights to the pick of Harvard graduates revoked due to their TrainingFromHell attitude towards interns, Louis hires an inspector to rectify the problem...who turns out to be nearly an OppositeSexClone of Louis himself. HilarityEnsues.
** In the same episode, Louis assists in one of Harvey's [[EurekaMoment Eureka Moments]]. Harvey will only say it once, but "Louis, you're the man". Louis's subsequent mouthing of "what. the. fuck?" after Harvey leaves is hilarious.
* Anything involving [[RightHandCat Bruno]]. [[spoiler:Even his euthanasia at the end of the episode is BlackComedy due to Louis's overblown reaction.]]
* Harvey meeting [[spoiler: Mike's grandmother]] and they start talking. His reaction to the below quote is ''priceless''.
-->'''Harvey''': Your grandson says nice things about you.
-->'''Edith''': Oh, he tells me you're quite the hardass.
* Harvey and Mike getting stoned together. Whatever isn't [[HeartwarmingMoments Heartwarming]] is hilarious, topped off by the two planning to sneak into Hardman's office to urinate on his carpet.
* When Donna is giving a clearly bummed out Harvey a friendly YouSuck speech over Mike not coming into work, she notes that unlike Mike, she doesn't have room for an eidetic since her head's already full of awesome in other ways.
* Donna and Harvey's prank on Louis. [[spoiler: They plaster his room office with his mugshot and captioned with different statements like "Major asshole". This includes replacing his photos, his files, ''everything'' with mugshots. And to top it off, they superglue his chair so that when he stands up, his pants rip. The best part? Not his OhCrap reactions. It's that he's actually happy about it because it means Harvey isn't (mostly) pissed at him.]]
* Louis seeing Nigel kiss Donna's hand at the elevator.
* Mike, lowly associate, runs into Darby, head of a multi-national law firm outside Harvey's office. They get along quite well, especially on the topic of Downton Abbey.
* Louis is having a great morning and he steps out of the elevator and sees [[spoiler: Harvey's name added to the firm's]]. His expression is priceless and he ends up taking a day off to recover from the shock. Later in the episode we see a flashback that shows that he had the exact same reaction to meeting Donna for the first time.
* Louis saying this. ItMakesSenseInContext....sorta.
-->'''Louis''': I eat cocks for breakfast, lunch and dinner....and it's delicious. Mmm mmm mmm!
* When Mike returns to the firm in Season 4, Katrina and him get into a little bit of a insult war (as befitting two proteges that take after their mentors). They're actually pretty happy to see each other but their history makes it very awkward to express any sort of friendship. It culminates in an an even more awkward hover-hand airhug.
* Donna and Rachel's "The most important emotional question" scene. This cannot be quoted because the question can only be mimed, and the answer is conveyed with eyebrow acting, but it can be seen [[https://youtu.be/L0Thv60VX98 here.]] After they agree to stop talking about Mike and Harvey, what happens next must be one of the worst ever attempts to pass the UsefulNotes/TheBechdelTest by two women with names and important jobs.
* When Louis' sister, Esther (Creator/AmyAcker) drops by, everyone is stunned to see this incredibly gorgeous woman and Louis come from the same gene pool. Even better? Louis assumes their amazement is because of how "we could be twins."
* Harvey getting under Jessica's skin by constantly referring to her relationship with Jeff. Finally:
-->'''Jessica''': (stopping suddenly & turning Harvey to face her & utterly deadpan as she stares into his eyes) Harvey, say banging to my face, one...more...time...
-->'''Harvey''': (pausing to consider it) I'm not going to...but it's NOT because I'm afraid of you.
* Harvey, Louis and Jessica getting high together in the season six premiere.
** After much reluctance, Louis finally reveals how much money he has. Harvey and Jessica are shocked as Louis dryly points out that he doesn't waste his money on designer clothes or other fancy things. Harvey, of course, just snaps Louis is cheap.
* Louis falls for his interior designer to the point he makes up having a home in the Hamptons he wants her to design just so she spends time with him. He then goes to Donna and asks she buy him a house in the Hamptons.
-->'''Donna''': You want to spend a fortune buying a home so that you can spend another fortune remodeling it?
-->'''Louis''': [[InsaneTrollLogic It's the only logical way that I can spend time with her.]]
-->'''Donna''': Is it?
-->'''Louis''': Yes. What other way can there possibly be?
-->'''Donna''': You could just ask her out.
-->'''Louis''': I can't.
-->'''Donna''': Why not?
-->'''Louis''': Jesus Christ, woman, why are you trying to sabotage my relationship?
-->'''Donna''': You have no relationship.
-->'''Louis''': That's what I'm trying to tell you!
* Louis wants to find "the perfect style of wood" to sway his designer. This leads to him making one "wood" line after another to Donna, completely oblivious to her biting her lip. When he tells her that "I need you to feel my wood," Donna can't take it anymore and runs out laughing as Louis just stares in confusion.
* Benjamin comes by to update Donna's computer and leads to her making one sexual innuendo line after another about her "hard drive." Later, Benjamin reveals that for two years, he's recorded everything Donna has said to make "The Donna," a data file for the right thing to say to everyone.
-->'''Benjamin''': You are without a doubt the most amazing legal secretary in the history of everything.
-->'''Donna''': Benjamin, that's the sweetest thing anyone's ever said to me.
-->'''Benjamin''': Okay but you said it about yourself two weeks ago.
-->'''Donna''': That I did.
** This leads to Donna taking "The Donna" along and bonding with "herself."
** Harvey's baffled reaction to it.
-->'''Harvey''': Did you just talk without saying anything?
-->'''Donna''': You do it all the time.
* When Louis is about to overreact on a case, Gretchen urges caution.
-->'''Gretchen''': There's more than one way to skin a cat.
-->'''Louis''': You mean, stuff a cat.
-->'''Gretchen''': Why would you want to stuff a cat?
-->'''Louis''': Cats are beautiful animals, only a barbarian would skin one.
-->'''Gretchen''': Louis, your mind isn't right.
* In flashbacks, we see Louis first meeting his shrink.
-->'''Shrink''': We have spent forty minutes of you listing every person who has disrespected you since birth.
-->'''Louis''': Are you kidding, we haven't even started.
** Louis describes Harvey as "a cross between Marlon Brando and Superman." The shrink needs a moment to think about that image.
