Children and fools cannot lie. 

Grow your tree of falsehood from a small grain of truth.

If you steal, do not steal too much at a time. You may be arrested. Steal cleverly, little by little.

Life is the art of being well deceived.

Your piping-hot lie is the best of lies.

It was the men I deceived the most that I loved the most.

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

The poor man is ruined as soon as he begins to ape the rich.

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

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

Honesty, for me, is usually the worst policy imaginable.

Cheating is more honorable than stealing. 

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