"We're going to need a bigger boat".
"Hello. My name is Inigo Montoya. You killed my father. Prepare to die."
And of course, my all time favourite (although it really is a bit of a cliched choice these days):
"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 Tannhauser gate.
All those moments will be lost in time, like tears in rain.
Time to die."
Ironicly one of my favorite Harvey Birdman Quotes is
"I've seen things you people wouldn't believe, and from this side only. The flight of a half man half bird, Dinosaurs nuzzling their young in pastures where strip malls should be, Cookies on dowels, all those moments lost in time, gone like eggs of a hookers stomach. Time to Die" - Phil Ken Sebben
"He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself." - Thomas Paine
"But such is the irresistable nature of truth, that all it asks, and all it wants is the liberty of appearing." - Thomas Paine
"A thing moderately good is not so good as it ought to be. Moderation in temper is always a virtue; but moderation in principle is always a vice." - Thomas Paine
"I've always found that the best way to be immortal is not getting yourself killed, like the best way to avoid divorce is not getting married."
- Tom Holt, Paint Your Dragon
Edit: i forgot this one:
"outside of a dog a book is man's best friend. inside of a dog it's too dark to read" - Groucho Marx
