shine, Mister Freeman. Rise and... shine. Not that I... wish to imply you have been sleeping on the job. No one is more deserving of a rest, and all the effort in the world would have gone to waste until... well, let's just say your hour has... come again. The right man in the wrong place can make all the difference in the world. So, wake up, Mister Freeman. Wake up and... *smell the ashes*... -G Man from Half-Life 2
Welcome. Welcome, to City 17. You have chosen, or been chosen, to relocate to one of our finest remaining urban centers. I thought so much of City 17, that I elected to establish my administration, here, in the citadel, so thoughtfully provided by our benefactors. I am proud to call City 17 my home. And so, whether you are here to stay, or passing through to parts unknown, welcome, to City 17. It's safer here. -Dr. Breen also from Half-Life 2

I can't seem to find the quotes I really, really like from Zelda - that is, basically all of Sheik's little poetry-lines before she teaches Link an ocarina song. Nocturne of Shadow speech is especially loved.
