Peter Quill: Dude, don't call us plucky. We don't know what it means. We're more optimistic, yes. I like your plan. Except, it sucks. So let me do the plan and that way it might be really good.
Drax: Tell him about the dance-off to save the Universe.
Tony Stark: What dance-off?
Peter Quill: It's not a thing.
Peter Parker: Like in Footloose, the movie?
Peter Quill: Exactly like Footloose. Is it still the greatest movie in history?
Peter Parker: It never was.
Tony Stark: Don't encourage Flash Gordon.
Peter Quill: Flash Gordon? That's a compliment. Don't forget, I'm half human. So that 50% of me that's stupid that's 100% you.
Okoye: When you said you were going to open Wakanda to the rest of the world, this is not what I imagined.
T'Challa: What did you imagine?
Okoye: The Olympics, maybe even a Starbucks.
Dr. Stephen Strange: Seriously? You don't have any money?
Wong: Attachment to the material is detachment from the spiritual.
Dr. Stephen Strange: I'll tell the guys at the deli. Maybe they'll make you a metaphysical ham and rye.
Wong: Wait, wait, wait. I think I have two hundred.
Dr. Stephen Strange: Dollars?
Dr. Stephen Strange: Which is?
Wong: A buck and a half.
Dr. Stephen Strange: What do you want?
Wong: I wouldn't say no to a tuna melt.
Thor: There are six stones out there. Thanos already has the Power Stone because he stole it last week when he decimated Xandar. He stole the Space Stone from me when he destroyed my ship and slaughtered half my people. The Time and Mind Stones are safe on Earth, they're with the Avengers.
Peter Quill: The Avengers?
Thor: The Earth's mightiest heroes.
Mantis: Like Kevin Bacon?
Thor: He may be on the team, I don't know.
