Snotlout: Unfortunately, due to several experiences in my youth, I cannot just 'walk up and join a circle of people talking', but it does sound lovely, thank you.
-----------------------------------------------------------
Heather: When I joined this friend group I thought you guys would be dealing with my bullshit.
*The Twins, Snotlout and Gustav continue screaming about mold water*
Heather: Not the other way around.
Hiccup, sarcastically: I dunno, sounds like you need to drink the mold water.
-----------------------------------------------------------
Tuffnut: The best way to gain someone's undying loyalty is by saving them from a perilous situation.
Ruffnut: So we’re just gonna wait until Hiccup is in danger and save him?
Tuffnut: Of course not, we’re going to create a situation that puts him in danger and then save them.

Throk: Whether or not I pay income taxes is none of the government's business.
Mala: No, well, actually, it is.
Throk: You don't know my name or what I look like, good luck finding me.
-----------------------------------------------------------
Valka: Can I ask you for a favor?
Stoick: I would literally die for you, but continue.
Valka: We need to talk about you starting sentences that way.

*at a zoo*
Ruffnut: What are they in for?
Fishlegs: Ruffnut, this isn't prison.
Ruffnut: So they can leave?
Fishlegs: No, but-
Ruffnut, pointing at a meerkat: I bet that one murdered someone.
-----------------------------------------------------------
Astrid: I fell—
Gustav: From heaven?
Astrid: No, I literally fell—
Gustav: In love with me the moment you saw me?
Astrid: MY ARM IS BROKEN!
Gustav: Okay, but do you think I'm pretty? Be honest.
-----------------------------------------------------------
Hiccup: I didn’t even realize how sarcastic I was being. It’s starting to become a problem, I think.
-----------------------------------------------------------
The Gang: You can do it Snotlout!
Tuffnut: But if you can't, at least your death will be quick, painless, and really cool to watch.
-----------------------------------------------------------
Dagur literally every time he and Hiccup had a confrontation: I came out here to have a good time and I'm honestly feeling so attacked right now.
-----------------------------------------------------------
Mala, entering the room: *Sees Dagur and leaves*
Dagur, watching Mala leave: There’s my monthly dose of Mala…
-----------------------------------------------------------
Gustav: I want to grow up and be like Snotlout!
Snotlout: That is called Acquiring Depression.
-----------------------------------------------------------
Heather: But when all hope seemed lost, I had an epiphany!
Heather, earlier: I'm going to throw myself into the sea.
-----------------------------------------------------------
Eret son of Eret: I hate when people ask me, 'What did you do today?' Buddy listen, I woke up at noon and then it was five p.m., okay? I don't KNOW!
-----------------------------------------------------------
Throk: Gatekeep, girlboss, and what's the other one again?
Mala: There isn't another one. You're crazy.
-----------------------------------------------------------
Tuffnut: Dude, I will never forgive Craigslist for banning me after I wrote a post seeking a sworn nemesis. Whoever reported that is obviously my nemesis but I was so pissed.
