Favorite and most memorable quotes from Firefly?!

I'll start with two of my favorites. How do I choose?

Jayne: "I'll kill a man in a fair fight. Or if I think he's gonna start a fair fight. Or if he bothers me. Or if there's a woman. Or if I'm gettin' paid. Mostly when I'm gettin' paid."

Book: "If you take sexual advantage of her, you're going to burn in a very special level of hell. A level they reserve for child molesters and people who talk at the theater."

EDIT: Here's a site to get you started if you can't remember many of them. http://www.thehallway.net/storage/fireflyquotes/index.htm They made me laugh so hard. Golly I miss this show!
