Someone who knows too much finds it hard not to lie.

An honest man is all right even if he’s an idiot…but a crook must have brains.

Cheating is more honorable than stealing. 

You can put wings on a pig, but you don’t make it an eagle.

Credulity forges more miracles than trickery could invent.

There was no treachery too base for the world to commit.

Life is the art of being well deceived.

And, after all, what is a lie? ’Tis but the truth in masquerade.

Children and fools cannot lie. 

Your piping-hot lie is the best of lies.
