CSI: Crime Scene Investigation, Season 9

(Sara and Grissom are watching the DVD of Warrick's custody hearing)

Woman [to Warrick]:
So what makes you think that you'd be a good father? You were raised by your grandmother. You never even knew your biological father.

Warrick:
Which is exactly why Eli needs to know his. Look, the most important thing you need to know about how to raise a child is how give a child love, and I've been loved. He says I've always tried to be a good man, and I've screwed up. And when I have there's always been one man in my life to set me straight. I've learned a lot from him, how to be fair, how to forgive, ... how to be inspired, how to inspire others.

Woman:
Sounds like a special person.

Warrick:
He is. If I could've picked my own father, I'da picked him. (Grissom is clearly touched and saddened at the same time)
