Thanos: The only matter I do not take seriously, boy, is you. Your politics bore me! Your demeanor is that of a pouty child. And apparently you alienated my favorite daughter, Gamora. I shall honor our agreement, Kree, if you bring me the orb. But return to me again empty handed and I will bathe the star-ways with your blood.
Rocket Raccoon: I don't think you even have a plan.
Peter Quill: I have part of a plan.
Drax the Destroyer: What percentage of a plan do you have?
Gamora: You don't get to ask questions after the nonsense you pulled on Knowhere!
Drax the Destroyer: I just saved Quill!
Peter Quill: We've already established that you destroying the ship I'm on is not saving me!
Drax the Destroyer: When did we establish that?
Peter Quill: Like three seconds ago!
Drax the Destroyer: Well I wasn't listening then, I was thinking of something else...
Groot: I am Groot.
Peter Quill: Well that's just as fascinating as the first 89 times. What is wrong with Giving Tree here?
Rocket Raccoon: Well he don't know talkin' good like me and you, so his vocabulistics is limited to 'I' and 'am' and 'Groot,' exclusively in that order.
Peter Quill: Well I tell you what, that's gonna wear real thin, real fast, bud.
Gamora: I'm a warrior, an assassin. I don't dance.
Peter Quill: Really? Well, on my planet, we have a legend about people like you. It's called Footloose. And in it, a great hero, named Kevin Bacon, teaches an entire city full of people with sticks up their butts that, dancing, well, is the greatest thing there is.
Gamora: Who put the sticks up their butts?
Drax the Destroyer: I just wanted to tell you how grateful I am that you've accepted me despite my blunders. It is good to once again be among friends. You, Quill, are my friend.
Peter Quill: Thanks.
Drax the Destroyer: This dumb tree is also my friend.
Drax the Destroyer: And this green whore is also...
Gamora: Oh, you must stop!
Peter Quill: She betrayed Ronan, he's coming for her. That's when you...[draws his finger across his throat].
Drax the Destroyer: Why would I want to put my finger on his throat?
Peter Quill: No, that's the symbol for slicing his throat.
Drax the Destroyer: I would not slice his throat, I would cut his head clean off.
