It Happened One Night (1934)

Ellie Andrews: I'll stop a car, and I won't use my thumb.
Peter Warne: What're you gonna do?
Ellie Andrews: It's a system all my own.

Peter Warne: I never did like the idea of sitting on newspapers. I did it once, and all the headlines came off on my white pants. On the level! It actually happened. Nobody bought a paper that day. They just followed me around over town and read the news on the seat of my pants.

Oscar Shapeley: Believe you me.
Ellie Andrews: Believe you me, you bore me to distraction.

Ellie Andrews: We'll get on a merry-go-round and never get off. Promise me we'll never get off.

Oscar Shapeley: What's a matter sister? You ain't sayin' much.
Ellie Andrews: It seems to me you're doing excellently without any assistance.

Joe Gordon: That's the way things go: you think you got a great yarn, and something comes along and messes up the finish - and there you are.

Ellie Andrews: What is it that we're supposed to be doing again?
Peter Warne: Hitchhiking.
Ellie Andrews: Well you've shown me an excellent example of the hiking part. When does the hitching come in?

Danker: Oh, I see, young people in love are never hungry.
