The Impostor:
Is it true he had eight hundred and fifty-seven affairs in three years?

Leporello:
To be exact, nine hundred and three.

Don Juan:
All girls are different. All wives are alike.

Don Juan:
Marriage is like a beleaguered city. Those that are out want to get in; those that are in want to get out.

Don Juan:
Lovely little girl!

Leporello:
She'd look awful by daylight.

Don Juan:
Well, who wants to see her by daylight?
