“It’s a funny thing–I suppose you’ve noticed it–the people who lie the most are nearly always the clumsiest at it, and they’re easier to fool with lies than most people, too. You’d think they’d be on the look-out for lies, but they seem to be the very ones that will believe almost anything at all. I suppose you’ve noticed that, haven’t you?”
“Yes.”
–From Dashiell Hammett’s The Thin Man
