Q. Where did the term "con man" (or "confidence man") come from?
A. "The name comes from 1849 when a man with many aliases was walking the streets of New York. He'd go up to people and ask if he knew them. He'd be so charming and gracious that they'd believe they did know him.
"He'd engage them in conversation, and then he'd say, 'Do you have enough confidence in me to lend me your watch?'
"The frame of that social encounter was so strong that the mark would hand over the watch, maybe internally mystified but not wanting to call out this account as strange. Then the confidence man would saunter off with the watch."
