Truth is still absolute. Believe that. Even when that truth is hard and cold, and more painful than you've ever imagined. And even when truth is more cruel than any lie. - Lucas Scott

Like so many others, this One Tree Hill quote profoundly summed up the lives of our favorite North Carolina teens. In the show's fourth season (2006-07), their emotions, relationships, life decisions, personal conflicts and tough choices made for more memorable lines than ever.

TV Fanatic is in the process of documenting the very best lines from the CW's long-running hit One Tree Hill, from 2003-present. Here are some highlights from Season Four ...

Whitey: When somebody says you can't do something you fight back. You prove them wrong. Nathan, where is the fire that made you the best player I ever coached?. Show me it's still there. If it's not, put down that ball and walk home. People love a guy who rises from the ashes. Remember that. | permalink

Brooke: What do virgins talk about?
Mouth: Oh, we like rainbows and kittens! | permalink

Chris Keller: Lookin' a little plump, Hales. What the hell, I've had bigger trunk in my bunk.
Haley: I'm pregnant, you idiot!
Chris: Oh. Dude! Totally not mine! | permalink

Brooke: I guess now it's hoes over psychos. | permalink

Rachel: (flicks Haley in the back of the head)
Haley: Oww!
Rachel: That was for soaking me at the last party. The bitch slap I deserved.
Haley: (throws drink on Rachel) That was for flicking me in the back of the head.
Rachel: I'm gonna miss this. | permalink

Nathan: You sure you're up for this old man?
Lucas: I could do this forever, little brother. | permalink

Rachel: Nathan looked good tonight, no wonder you're pregnant. | permalink

Lucas: Hey, I've been waiting for you
Peyton: I think we've waited long enough. | permalink

Haley: Why is it that it's so much easier to forgive a stranger than someone you love? | permalink

Shelly: Well, the door's always open.
Brooke: Just like Rachel's legs. | permalink

Brooke: I'm not book smart, I'm Brooke smart and there is a big difference. | permalink
