Anna Brady plans to travel to Dublin, Ireland to propose marriage to her boyfriend Jeremy on Leap Day, because, according to Irish tradition, a man who receives a marriage proposal on a leap day must accept it.

Bride: May you never steal, lie, or cheat, but if you must steal, then steal away my sorrows, and if you must lie, lie with me all the nights of my life, and if you must cheat, then please cheat death because I couldn't live a day without you. Cheers!
Anna: When my 60 seconds came around i realized i had everything i ever wanted... but nothing i really needed. and i think what i need is here. and i came all this way to see if you maybe think so too. If you do, well... i don't really have plans past that, which is new for me. So, Declan O'Callhan and i should probably learn your middle name, here is my proposal; i propose we not make plans, i propose we give this thing a chance and let it work out how it works out. so what do you say, do you wanna not make plans with me?
Declan: [slams Anna's suitcase on the ground] How does that work?
Anna: Can you be careful with that, it was a gift from my boyfriend!
Declan: He bought you a suitcase?
Anna: It's a Vuitton.
Declan: What?
Anna: A Louis Vuitton?
Declan: Come on. Ah, is it yourself Louis? Can I give you a hand getting into the car Louis? She named her suitcase, she's a crackpot.
Declan: I don't want not to make plans with you. I want to make plans with you.
Anna: You do?
Declan: Yeah I do.

Anna: [as she forces Declan awake] You lying, deceiving, son of a - Get up, get up, get up!
Declan: Wha-what?
Anna: Oh? Heads you win, tails I lose.
Declan: [smirks] Oh, you finally got that did you? Well then, good for you.
Anna: Up, get up! This is my bed. Liars forfeit.
[as she sniffs him]
Anna: And take a shower, you smell.
Declan: [shakes head] You can see right through the curtain.
Anna: Can you?... can you?
Declan: [as he runs to the shower] Okay, liars forfeit, liars forfeit! No peeking!
Declan: Mrs. O'Brady Callhan. Where the hell are you going?
Anna: You said no.
Declan: I didn't say no. I didn't say anything.
Anna: You walked away.
Declan: I was getting something.
Anna: Really? That was a good time to go get something?
Declan: Yeah, it was actually.
[Presents Anna with a ring]
Anna: You fried my blackberry
Declan: You fried the whole village, idiot!
Anna: What about my suitcase?
Declan: Don't worry about Louie, I'll get it!
Declan: Just put 'em the wash; they'll be grand.
Declan: Dublin, huh? Let me tell you something about Dublin. Dublin is a city of chances and cheats and back stabbing snakes. It is a city where the worst of humanity collects the poison of their country. I wouldn't advise you to go there.
Declan: [picking Louis Vitton's bag from Anna] I got Louie for you!
Anna: Do you wanna talk about it?
Declan: Listen, Bob. You're not in America now, you're in Ireland. So have a drink and shut up.
Declan: which one of you bollocks thinks my chicken is dry? You? You?
Declan: What the hell are you doing here?
Anna: could you maybe be nice for just a second, i just flied 3,000 miles just to get here
Declan: Why don't you stop trying to control everything in the known universe. It's dinner. Have a little faith that it will all work out.
Anna: What are you, the Lucky Charms leprecaun?
Declan: Jesus Christ!
Anna: ...is Lord.
