Misha Collins, who plays the beautiful Angel who always roots for the Winchester brothers in The CW series "Supernatural", is turning 41 on Thursday, 20 August. What better way to celebrate the occasion than with a list of some of the best quotes of the beloved Cas from the seven seasons of "Supernatural".

On the Head of a Pin (Season 4 Episode 16)

Dean: You guys don't walk enough. You're gonna get flabby. You know, I'm starting to think Junkless has a better sense of humor than you do.
Castiel: Uriel's the funniest angel in the garrison. Ask anyone.

99 Problems(Season 5 Episode 17)

Castiel: [Castiel appears in the motel room] I got your message. It was long your message. I find the sound of your voice grating.
Sam: What's wrong with you? [Castiel wobbles]
Sam: Are you... drunk?
Castiel: No! Yes.
Sam: What the hell happened to you?
Castiel: I found a liquor store.
Sam: And?
Castiel: And I drank it!

Cages Heat (Season 6 Episode 10)

Castiel: (while watching porn) That's very complex
Dean: M-hm
Castiel: If the pizzaman truly loves this babysitter, why does he keep slapping her rear?... Perhaps she's done something wrong.
Dean: You're watching porn? Why?
Castiel: It was there.
Dean: You don't watch porn in a room full of dudes. And... you don't talk about it. Just turn it off. Castiel looks between his legs
Dean: Oh, now he's got a boner

Survival of the Fittest (Season 7 Episode 23)

Dean: Hey, there. So, Cas, what's, uh, what's the word?
Castiel: Well, Dean, I've been thinking. Monkeys... are so clever, and their sensible in that they leave the skins on the bananas that they eat. Is it really necessary to test cosmetics on them? I mean, how important is lipstick to you, Dean?

Goodbye Stranger (Season 8 Episode 17)

Meg: Why are you so sweet on me, Clarence?
Castiel: I don't know. And I still don't know who Clarence is.
Meg: Would it kill you to watch a movie, read a book?
Castiel: A movie, no. But with a book with the proper spells - yeah, it could, theoretically, kill me.

Stairway to Heaven (Season 9 Episode 22)

Castiel: (Reading a code written at the door of a building) It's Enokian. I believe it's some sort of riddle. Why is six afraid of seven? Now... I assume it's because... seven is a prime number. And prime numbers can be intimidating.
Sam: It's because seven ate nine. (the door opens)
Castiel: It's word play. And the answer is the key like the Doors of Durin in Lord of the Rings.
Sam: Wait a second. You know about The Lord of the Rings?
Castiel: I'm very pop culture savvy now.

Inside Man(Season 10 Episode 17)

Metatron: Well, howdy, fellas.
Bobby: This is the Scribe of God? He looks like a Fraggle.
Metatron: I'm gonna take that as a compliment. That was an excellent program.
Castiel: Metatron, we are here...
Metatron: I know why you're here, "Asstiel", and I'm not interested. I told you I would rather die then let Dean Winchester use me as his personal punching bag again.
Castiel: Don't worry. Dean's not involved. You're gonna be my punching bag.
