Roadblock

Diane:
Someday you're going to want something nice and expensive that you can't afford on a detective's salary.

Joe Peters:
Like what?

Diane:
Like me.

Diane:
You're a nice guy, Honest Joe, but you're not in the right league. I'm aiming for the World Series.

Mrs. MacDonald:
Take plenty of warm clothes. It's awful cold in the mountains.

Joe Peters:
Who gets cold on a honeymoon?

Mrs. MacDonald:
Oh, Mr. Peters! [chuckles]

Egan:
[about Joe after he beats up DeVito] I thought he was an easy-going guy.

Harry Miller:
He was - until he got married.
