“No. No, you can’t… STOP. Please don’t go away. Please? No one’s ever stuck with me for so long before. And if you leave… if you leave… I just, I remember things better with you. I do, look. P. Sherman, forty-two… forty-two… I remember it, I do. It’s there, I know it is, because when I look at you, I can feel it. And-and I look at you, and I… and I’m home. Please… I don’t want that to go away. I don’t want to forget.”
2. My Girl
“Where are his glasses? He can’t see without his glasses!” (My Girl)
F*@k this movie, the kids I babysit can’t respect me after I cried like a little bitch during this scene.
3. Forrest Gump
“Is he smart or is he…like me?” God d@mmit why do these threads come up when there’s onions being chopped.

5. Toy Story 3
“Now Woody, he’s been my pal for as long as I can remember. He’s brave, like a cowboy should be. And kind, and smart. But the thing that makes Woody special, is he’ll never give up on you… ever. He’ll be there for you, no matter what.”
“Dear sweet Littlefoot, do you remember your way to the great valley?”
“I guess so, but why do I have to know if your gonna be with me?”
“My family is with me today. They wanted to come with me. To be honest with you, I wasn’t sure how I’d feel coming back here. Every day I think about what you said to me that day on the bridge. I tried to live my life the best that I could. I hope that was enough. I hope that, at least in your eyes, I’ve earned what all of you have done for me.”
“Doc, short of being dead, what the hell are you doin’ this for anyway?”
“Wyatt Earp is my friend.”
“Hell, I got lots of friends.”
“When you comin’ home Harry?”
“Soon. You holdin’ out, right?”
“Harry, can you come today?”
The scene right before everything crumbles for Harry and Marion in ‘Requiem for a Dream’. Gosh, the scene just breaks my heart.
“Today is my birthday and its a special one because you once told me that when you came back we might be the same age. Well I’m the same age that you were when you left and it’d be really great if you came back soon.”
Pippin: “I didn’t think it would end this way.”
Gandalf: “End? No, the journey doesn’t end here. Death is just another path… One that we all must take. The grey rain-curtain of this world rolls back, and all turns to silver glass… And then you see it.”
Pippin: “What? Gandalf?… See what?”
Gandalf: “White shores… and beyond, a far green country under a swift sunrise.”
Pippin: [smiling] “Well, that isn’t so bad.”
Gandalf: [softly] “No… No it isn’t.”
“It’s not your fault” (the whole scene).
13. Blade Runner
“I’ve… seen things… you people wouldn’t believe. Attack ships on fire off the shoulder of Orion; I watched c-beams glitter in the dark near the Tannhäuser Gate… All those… moments… will be lost, in time, like [chokes up] tears… in… rain. Time… to die.”
The best thing about this line is, it was almost completely improvised by Hauer.
