My friend, Tony, does prop work in Hollywood. Before he was big and famous, he would sell jewelry and such at Ren Faires and the like. One day I'm there, shooting the shit with him, when a guy comes up and looks at some of the crystals that Tony is selling. he finally zeroes in on one and gets all gaga over the bit of quartz. He informs Tony that he's never seen such a strong power crystal. Tony tells him it a piece of quartz. The buyer maintains it is an amazing power crystal and demands to know the price. Tony looks him over for a second, then says "If it's just a piece of quartz, it's $15. If it's a power crystal, it's $150. Which is is?" The buyer actually looked a bit sheepish as he said quietly "quartz", gave Tony his money and wandered off. I wonder if he thought he got the better of Tony.
