Don Lockwood: [singing] That's the Broadway Melody!

Don Lockwood: [to Kathy, after she jumps out of the cake] Well, if it isn't Ethel Barrymore.

Don Lockwood: [to the press] They sent me to the finest schools, including dancing schools. That's where I first met Cosmo. And with him I used to perform for all of Mom and Dad's society friends.

Don Lockwood: [while filming a love scene] Why, you rattlesnake! You got that poor kid fired.
Lina Lamont: That's not all I'm gonna do if I ever get my hands on her.
Don Lockwood: I never heard of anything so low. Why did you do it?
Lina Lamont: Because you liked her. I could tell.
Don Lockwood: So that's it. Believe me, I don't like her half as much as I hate you, you reptile.
Lina Lamont: Sticks and stones may break my bones...
Don Lockwood: I'd like to break every bone in your body.
Lina Lamont: You and who else, you big lummox?

Don Lockwood: Are you doing anything tonight, Miss Lamont?
[she shakes her head "no"]
Don Lockwood: Well's that's funny - *I'm* busy.

Don Lockwood: Cosmo, call me a cab.
Cosmo Brown: OK, you're a cab.

Don Lockwood: Dignity. Always, dignity.

Don Lockwood: I do hope you're going to favor us with something special tonight.
Kathy Selden: Please!
Don Lockwood: Say, Hamlet's soliloquy, or the balcony scene from "Romeo and Juliet."
Kathy Selden: Mr. Lockwood!
Don Lockwood: Don't be shy. You'd make about the prettiest Juliet I've ever seen. Really.

Don Lockwood: I just had to tell you how good you were.
Kathy Selden: Excuse me.
Don Lockwood: No, no, don't go.
[pointing to cake she came out of at beginning of scene]
Don Lockwood: Now that I know where you live I'd like to see you home.

Don Lockwood: I'm no actor. I never was. Just a bunch of dumb show. I know that now.
Cosmo Brown: Well, at least you're taking it lying down.
Don Lockwood: No. No kidding, Cosmo. Did you ever see anything as ridiculous as me on that screen tonight?
Kathy: Yeah, how about Lina?
Don Lockwood: All right. I ran her a close second. Maybe it was a photo finish. I'm through, fellas.
Kathy: Don, you're not through!
Cosmo Brown: Why of course not. Why, with your looks and figure, you could drive an ice wagon or shine shoes!
Kathy: Block hats!
Cosmo Brown: Sell pencils!
Kathy: Dig ditches!
Cosmo Brown: Or worse still, go back to vaudeville.
