The wicked are always ungrateful.
The pen is the tongue of the soul; as are the thoughts engendered there, so will be the things written.
Too much sanity may be madness!
Mere flimflam stories, and nothing but shams and lies.
Give the devil his due.
You are a devil at everything, and there is no kind of thing in the 'versal world but what you can turn your hand into.
