Donnie Darko (2001)

Donnie: Life isn't that simple. I mean who cares if Ling Ling returns the wallet and keeps the money? It has nothing to do with either fear or love.
Kitty Farmer: Fear and love are the deepest of human emotions.
Donnie: Okay. But you're not listening to me. There are other things that need to be taken into account here. Like the whole spectrum of human emotion. You can't just lump everything into these two categories and then just deny everything else!

Donnie: You are such a fuckass.
Elizabeth: Did you just call me a fuckass? You can go suck a fuck.
Donnie: Oh, please, tell me Elizabeth, how exactly does one suck a fuck?

Dr. Lilian Thurman: Donnie, an atheist is someone who denies altogether the existence of God. You're an agnostic. An agnostic is someone who believes that there can be no proof of the existence of God, but does not deny the possibility that God exists.

Gretchen: You're weird.
Donnie: Sorry.
Gretchen: No, that was a compliment.

Gretchen: Some people are just born with tragedy in their blood.

Gretchen: What if you could go back in time, and take all those hours of pain and darkness and replace them with something better?

Donnie: Why do you wear that stupid bunny suit?
Frank: Why are you wearing that stupid man suit?

Donnie: I promise, that one day, everything's going to be better for you.

Donnie: I made a new friend today.
Dr. Lilian Thurman: Real or imaginary?
Donnie: Imaginary.

Gretchen: My mom had to get a restraining order against my stepdad. He has emotional problems.
Donnie: Oh, I have those too! What kind of emotional problems does your dad have?
Gretchen: He stabbed my mom four times in the chest.
Donnie: Oh.

Donnie: Where did you come from?
Frank: Do you believe in time travel?

Donnie: How can you do that?
Frank: I can do anything I want. And so can you.

Samantha Darko: Why do I have to sleep with Donnie? He stinks.
Donnie: When you fall asleep tonight, I'm gonna fart in your face.
