I read Lee Trevino's books on how to Hustle.
Dude was the King
Most classic was for him to go on to one of Dallas Par 3s where he would play with a two liter glass Dr Pepper bottle against random pigeons.
He could usually get up in about three or four and then one or two putt. Meanwhile, he would talk massive shit to his opponent, getting into their head.

"You don't want to be thinking about the water now."
"Oh, I'm not!"
"Then why are you pulling an old ball out of your bag??"
