Michael: [speaking to Carlo] Only don't tell me you're innocent.
 

Because it insults my intelligence and makes me very angry.



Don Corleone: I spent my whole life trying not to be careless. Women and children can be careless. But not men.





the godfather (book) i consider a great business book, a lot of subtle lessons there

how many people have you killed so far?

I'm scared to imagine what happens to webmasters that break WC's TOS...

lol, some of the characters are eloquent:

Michael: Some people will pay a lot of money for that information; but then your daughter would lose a father, instead of gaining a husband.


practical:

Don Corleone: I'm a superstitious man, and if some unlucky accident should befall Michael - if he is to be shot in the head by a police officer, or be found hung dead in a jail cell... or if he should be struck by a bolt of lightning - then I'm going to blame some of the people in this room; and then I do not forgive. But with said, I pledge - on the souls of my grandchildren - that I will not be the one to break the peace that we have made today.

tongue-in-cheek humor, to ease tension:

Clemenza: All right, you just shot 'em both. Now what do you do?
Michael: Sit down and finish my dinner.

keep your cards close to your chest:

Don Corleone: Never let anyone outside the family know what you're thinking.

being perceptive:

Michael Corleone: I know it was you Fredo. You broke my heart. You broke my heart!
