Well, this is what I figured could be a fun thread: a place to post quotes that are inspirational, funny or otherwise interesting. I'll be starting off with a few of my favourites:

The sky calls to us. If we do not destroy ourselves, we will one day venture to the stars. ~Carl Sagan

I know that the molecules in my body are traceable to phenomena in the cosmos. That makes me want to grab people in the street and say, "have you heard this?" ~Neil deGrasse Tyson

It never gets easier, you just go faster. ~Greg LeMond

Some people believe football (soccer) is a matter of life and death. I'm very disappointed with that attitude. I can assure you it is much, much more important than that. ~Bill Shankly

Fail to prepare, prepare to fail. ~Roy Keane

When you have eliminated the impossible, whatever remains, however improbable must be the truth. ~Sir Arthur Conan Doyle

Nothing is too wonderful to be true, if it be consistent with the laws of nature. ~Micheal Faraday

And finally, just for funzies, probably the funniest quote from the 2010 Olympics:
I think I have seen too much porn in the last 14 days. I have the room next to Petter (Northug) and every day there is noise in there. So I think that is the reason I @#$%^& up. ~Odd-Bjørn Hjelmeset

A few of the ones I like:

When you know better, you do better. ~ Maya Angelou

Reality is merely an illusion, albeit a very persistent one. ~ Albert Einstein

Friends Don't Let Friends Vote Republican ~ bumper sticker

"You from the States?" "Yeah, but don't hold it against me." "I'll try not to... Just try not to say anything too loud or crass." ~ movie In Bruges

"See, how it works is, the train moves, not the station." ~ movie A League of Their Own

So it goes. ~ Kurt Vonnegut

"tired of crown searching, telepathy and hope. watch the stars, predict the past and change the world with a silver eclipse. the only thing that's permanent is destruction, we're all going to disapear, trying to leave something more permanent than myself." Sarah Kane
