Dr. Armstrong: Promise me you will stick within the letter of the law, and I'll see what I can do.

Captain Thorton: "Make yourself easy, sir. I am in the execution of my orders. And as you say you are a friend to King George, you will be glad to learn that it is impossible that this gang of ruffians, whose license has disturbed the country so long, can escape the measures now taken to suppress them. The horse squadron of militia, commanded by Major Galbraith, is already joined by two or more troops of cavalry, which will occupy all the lower passes of this wild country; three hundred Highlanders, under the two gentlemen you saw at the inn, are in possession of the upper part, and various strong parties from the garrison are securing the hills and glens in different directions. Our last accounts of Rob Roy correspond with what this fellow has confessed, that, finding himself surrounded on all sides, he had dismissed the greater part of his followers, with the purpose either of lying concealed, or of making his escape through his superior knowledge of the passes.
Bailie Jarvie: "I dinna ken; there's mair brandy than brains in Garschattachin's head this morning—- And I wadna, an I were you, Captain, rest my main dependence on the Hielandmen—- hawks winna pike out hawks' een. They may quarrel among themsells, and gie ilk ither ill names, and maybe a slash wi' a claymore; but they are sure to join in the lang run, against a' civilised folk, that wear breeks on their hinder ends, and hae purses in their pouches."

"Well Pennyroyal, we all have to step outside our comfort zones—grow, expand, do things we normally never fathom doing—which is why I'm proposing a little supervillain/superspy team-up. I already have a brilliantly terrifying plan. They say revenge is a dish best served cold, but I think the portions are big enough for us to split."

Baal: I cannot believe I am even considering cooperating with a female of the Tauri... and a Tok'ra.
Selmak: This was not my idea, believe me.

Luigi: Oh, mama-mia... what are we gonna do, Mario?! We're just-a two guys from Brooklyn! There's no way we can deliver all of these presents to all the good little paisanos in one night-

Mario: Well... okie-dokie! Let's-a-go!
I’d never heard the words
Enemies for centuries,
Until there was a third
In the ping-pong match of constant desire

Now we've got that sympathy
What I'm to you,
You are to me,
Let's go

"Let the vampires join us. In this war, we no longer have the luxury of choosing our comrades."
General Tazri, Magic: The Gathering

"At his core, Dexter King is a thoroughly unpleasant human being. He is bitter, hateful, possessed of attitudes towards race and gender that can only be described as horrifying, and generally as spiteful a frustrated autocrat as one can imagine. Furthermore, he was this way before his lungs started to go, and in all probability, most Garou would gladly take the opportunity to rid the planet of such a blot on its escutcheon. But faced with the choice of Dexter or Jeremy, Garou seeking to take King down might find themselves forced to make a most unlikely and unpalatable alliance with the terrible old man of King Breweries."
Werewolf: The Apocalypse — Subsidiaries: A Guide to Pentex

You now shelter with the Tzimisce, who are more than happy to help you continue your studies, particularly with regard to the body. You're not entirely comfortable with their outlook on existence, but it's better than facing the pyre. Still, there are nights when you stuff wool in your ears before you sleep, trying to block out the sounds coming from the cellar.

We stand united with these sorcerers in our mutual contempt for the Tremere. We have long-standing alliances with certain orders of wizards — alliances still maintained, albeit clandestinely. Such alliances have proved most auspicious for our clan, for mages possess powers as formidable as they are subtle. The order known as "Progenitors" is a particularly intriguing body; we could learn much from it.
...Not that any of these things will stop us from draining them to desiccated husks and liquefying their bones into pus once their usefulness has ended. Still, one must give credit where credit is due...

The Bloodied Wolf/Mephisto, Diablo IV

Shepard: I want you to put a bullet in his head... but we're all making some sacrifices today.

John Marston: My side wasn't chosen, my side was given. I'd kill you a hundred times before I killed Dutch, if that were an option.
Agent Edgar Ross: Hallelujah! I think we are finally reaching an understanding, Mr. Marston.

"Just for tonight, just for kicks, let's do what we do best. The skills we usually sharpen on each other's skulls, let's use them on a common foe instead. Imagine! Imagine the look on the evil eight-headed farmer's faces when he sees the dog, the cat and the rat all coming down on him, packing heat and purpose! (Evil Laugh) Priceless! We can get back to playing chin music on each other tomorrow — promise!"

Price: Makarov, this is Price. Shepherd's a war hero now. He's got your operations playbook and he's got a blank check. Give me what you got on Shepherd, and I'll take care of the rest. ...I know you can hear me on this channel, Makarov. You and I both know you won't last a week.
Makarov: And neither will you.
Price: Makarov... you ever hear the old saying... the enemy of my enemy is my friend?
Makarov: Price, one day you're going to find that cuts both ways. Shepherd is using Site Hotel Bravo. You know where it is. I'll see you in hell.
Price: Looking forward to it. Give my regards to Zakhaev if you get there first.

Nathan Drake: Yeah, likewise pal. Now let's do this!

Oberon: Senji Muramasa, was it? It sounds like you want to take out Queen Morgan as much as we do. How about we team up, just until we defeat her? Yesterday's enemy is today's friend and all that. Besides, don't you think it would be better for us to put all our wood behind one arrow, so to speak?
Senji Muramasa: ...Good point. I doubt I'll be gettin' any other help out here. Sounds like a pretty good suggestion to me.
Da Vinci: ...Hmm. What do you think, Master? I know Senji Muramasa's one of the Foreign God's Disciples, but he's also always been relatively reasonable.

Bowser: All this power AND looks too! I know! You're thinking... "A big, strong guy like him would be great to have along!" right? I'm gonna do something I may regret later... I'll let you join my minions. You can thank me later...

Penny: I always felt like I had this little safety zone, because a lot of the things I cared about... I didn't really care about. I don't really need the perfect shoes, it's just fun to pretend I do. And I could look at her and not really care. So she fools peons into thinking she's hot, so what? Who'll care in a few years? We're all going to college and startups. Except... so is she. She'll go far in this world. And she'll get whatever she wants... by making dozens, hundreds, of people feel feel like you do now. And we gave her that power. So it'll be our fault. Unless...

"Oh man, cooperation amongst enemies! I swear we'd be like in a Saturday night Christmas Special or something."

Grif: So now we're forced to work together. How ironic.
Simmons: No, that's not ironic. Ironic would be if we had to work together to hurt each other.
Donut: No, ironic would be instead of that guy kidnapping Lopez, Lopez kidnapped him.
Sarge: I think it would be ironic if our guns didn't shoot bullets, but instead squirted a healing salve that cured all wounds.
Caboose: I think it would be ironic if everyone was Made of Iron.
Church: Okay. (slowly) We're all agreed that while the current situation is not totally ironic, the fact that we have to work together is odd in an unexpected way that defies our normal circumstances. Is everybody happy with that?

ryan218: Agreed. 'The enemy of my enemy is my friend.'
starswordc: Wrong. The enemy of my enemy might be a potential ally, but when enemy #1 is already known for certain from multiple encounters to be composed entirely of omnicidal maniacs who have never once claimed to be otherwise, I'd at least give serious thought to taking a look at whether joining up with enemy #2 might be more useful. Especially when your standing orders preclude going with enemy #1. If we're going with cliches, in this case "the devil you know" is Satan himself.

Technoblade: Listen. Listen, Bad, I didn't wanna work with this guy either, but this Egg, this Egg, it's going too far. It's warpin' people's minds, it's controllin' them, it has no plans on stoppin', until it controls the entire worl– I swear to God, if this dog keeps dying on this magma block– it has no plans on stoppin', and this Egg stands for everything... it's the epitome of everything I stand against as an anarchist! And if I don't stop it now, it'll be the end of the world. So yeah, I'm workin' with Quackity!
