@George,
My favorite, from Scroooge, the film adaptation:
Spirit of Christmas Present: My time with you is at an end, Ebenezer Scrooge. Will you profit from what I've shown you of the good in most men's hearts?
Ebenezer: I don't know, how can I promise!
Spirit of Christmas Present: If it's too hard a lesson for you to learn, then learn this lesson!
[opens his robe, revealing two starving children]
Ebenezer: [shocked] Spirit, are these yours?
Spirit of Christmas Present: They are Man's. This boy is Ignorance, this girl is Want. Beware them both, but most of all, beware this boy!
Ebenezer: But have they no refuge, no resource?
Spirit of Christmas Present: [quoting Scrooge] Are there no prisons? Are there no workhouses?
