Cable: Dubstep's for pussies!
Wade Wilson: You're so dark. Are you sure you're not from the DC universe?
Wade Wilson: With this collar on, my superpower is just unbridled cancer. Give me a bow and arrow and I'm basically Hawkeye.
Wade Wilson: Sorry I'm late. There was a bunch of handicapable children stuck in a tree. I had to...
Vanessa: Uh-uh.
Wade Wilson: You're right. I was fighting a caped badass, but then we discovered that his mom is named Martha, too.
Wade Wilson: [to Vanessa] I hope we sharpened the cream cheese spreader.
[Wade throws the spreader into the gunman's head, killing him]
Wade Wilson: [turns on time-travel device] I'll be right back. We're definitely naming our kid Cher!
Weasel: And last but not least... Peter.
Deadpool: Any power you wanna tell us about?
Peter: I don't... I don't have one. Um, I just saw the ad.
Deadpool: No superpowers at all?
Peter: Uh, I have both type 1 and 2 diabetes.
Deadpool: Ow! Oh!
Weasel: That's all the diabetes.
Deadpool: Right. Yeah, you got them all. If you find a type 3, let us know. Yeah. You're in.
Cable: I'm retrieving something from my utility bag.
Weasel: It's a goddamn fanny pack and you know it, you sick son of a bitch! The difference is night and day.
Deadpool: [fighting the Juggernaut] Hey, big guy, the sun's getting real low.
[from trailer]
Cable: I was born into war, bred into it. People think they understand pain, but they have no concept of it. What's the most pain you've ever felt? Maybe the kind that leaves you more machine than man.
Deadpool: [halts trailer] Wait, no, STOP! What in the actual ass? Dale! Why, why are the visual effects not done? It's a metal arm!
It's not like we're trying to remove a mustache! Oh fuck it, I'll do it myself...
Deadpool: I don't speak Cantonese, Mr...
[looks at card, then tosses it]
Deadpool: Well, I'm not even going to attempt that. But I did take eighth grade Spanish, so donde esta la biblioteca? Which literally translates to: I don't bargain, pumpkin-fucker.
