Ok, more a monologue than a quote, but my all-time favorite movie scene, ever (from Rocky):
Took ya long enough to get here, after 10 years you come to my house? Whatsa matter, you don't like my house? My house stink? Thats right it stinks! I didn't ask no favors from you! Don't swarm around me...And the best part... ^^That was all from memory...
Talk about your prime.. what about my prime Mick? At least you had a prime! I ain't have no prime, I ain't have nothing! Legs are going, everythings going, nobody's getting to know nothing.
Guy comes up offers me a fight, big deal; "Wanna fight the fight?" Yeah, I'll fight the big fight.. I'm gonna go and fight that big fight and do know whats gonna happen to me? I'm gonna get that! I'm gonna get that! and you wanna be ringside and see it? Do ya? You wanna help me out? Do you wanna see me get my face kicked in?
My legs ain't working, nothings working.. they go "go on, fight the champ" Yeah, I'll fight him, I'll get my face kicked in.
And you come around here.. You wanna move in here with me? Come on in, its a nice house. Real nice, come on in and move...it stinks! This whole place stinks!
You wanna help me out? Well help me out! C'mon help me out.. I'm standing here.
and my second Favorite from Star Wars: Episode III - Revenge of the Sith:
"You were the chosen one! It was said that you were to destroy the Sith not join them! Bring Balance to the force... not leave it in darkness!
You were my brother Anakin, I loved you. "
