Lying

"Ce mensonge immortel."

"Had I a heart for falsehood framed. I ne'er could injure you."

"This shows that liars ought to have good memories."

"That a lie which is half a truth is ever the blackest of lies; That a lie which is all a lie may be met and fought with outright— But a lie which is part a truth is a harder matter to fight."

"And he that does one fault at first, And lies to hide it, makes it two."

"An animal may be cunning and ferocious enough, but it takes a real man to tell a lie."

"I give him joy that's awkward at a lie."
