Grey's Anatomy is one of televisions most popular medical dramas. The show, which airs on ABC Thursday nights, keeps fans tuned in each week to find out what is going to happen and to whom.

If you are a fan of Grey's Anatomy -- and who isn't? -- (or even if you are just tuning in for the first time), I hope you enjoy these sharp, hilarious, and revealing quotes we've compiled from the Grey's Anatomy characters:

1. Meredith Grey: "I've heard that it's possible to grow up - I've just never met anyone who's actually done it. Without parents to defy, we break the rules we make for ourselves. We throw tantrums when things don't go our way, we whisper secrets with our best friends in the dark, we look for comfort where we can find it, and we hope - against all logic, against all experience. Like children, we never give up hope."

2. Izzie Stevens: "You are a doctor now, parental disappointment ends with a medical degree."

3. Cristina Yang: "Everyone's back. Everyone's back except her. And I listen to her. Everyday, about her McLove life. Her McDreamy, her McCrap. And the one day, the one day I have a thing she disappears."

4. Meredith Grey: "I'm a surgeon. I do the rescuing. You are not my knight in shining whatever."

5. Miranda Bailey: "I have five rules. Memorize them. Rule number one, don't bother sucking up. I already hate you, that's not gonna change."

6. Mr. Levangie: "I know it's not perfect, but it's life. Life is messy sometimes."

7. Cristina Yang: " You know what? For just a moment, I'm not Dr. Yang and you're not Dr. Shepherd. You're the guy who screwed up my friend. The guy who drove her to get a dog she can't keep, the dog she only got because her boyfriend lied to her about his wife."

8. George O'Malley: "Got a head count of how many patients you two lied to the past month?"

9. Derek Shepherd: " There is a land called Passive Agresseva, and you are their queen."

10. Cristina Yang: "You know, I know a liar when I see one because I am a liar."

11. Izzie Stevens: "You know what? You're gonna have to get over the whole man thing, George! We're women! We have vaginas! Get used to it!"

12. Cristina Yang: "I need a drink, a man, or a massage. Or a drunken massage by a man."

13. Miranda Bailey: "An intern was reassigned so he's mine now. Have him shadow you for the day, show him how I do things."

14. Richard Weber: "Just shut up and count backwards already."

15. Derek Shepherd: "You wanna get married? You never told me, and I never asked. And now we have a problem."

16. Miranda Bailey: "You do that. In the meantime, why don't we pretend it's you on this table, and give this a try."
