The Shawshank Redemption (1994)
Joseph Ragno: Ernie
Red : These walls are funny. First you hate 'em, then you get used to 'em. Enough time passes, you get so you depend on them. That's institutionalized.
Heywood : Shit. I could never get like that.
Ernie : Oh yeah? Say that when you been here as long as Brooks has.
Red : Goddamn right. They send you here for life, and that's exactly what they take. The part that counts, anyway.
[after Brooks held a knife to Heywood's throat]
Andy Dufresne : I just don't understand what happened in there.
Heywood : Old man's crazy as a rat in a tin shithouse, is what.
Red : Oh Heywood, that's enough out of you!
Ernie : I heard he had you shittin' in your pants!
Heywood : Fuck you!
Red : Would you knock it off? Brooks ain't no bug. He's just... just institutionalized.
Heywood : Institutionalized, my ass.
Red : The man's been in here fifty years, Heywood. Fifty years! This is all he knows. In here, he's an important man. He's an educated man. Outside, he's nothin'! Just a used up con with arthritis in both hands.
