Roberto is a New York art connoisseur and one day, he’s walking in Brooklyn and notices a mangy little kitten lapping up milk from a saucer in front of a restaurant called Moishe’s Deli. He quickly realizes with a shock that the saucer was a very rare and precious piece of pottery. He strolled into the store and offered $10 for the cat.
"It's not for sale," said Moishe.
"Look," said Roberto, "that cat is dirty and undesirable, but I'm eccentric. I like cats that way. I'll raise my offer to $50."
"It's a deal," said Moishe, and pocketed the money.
"For that sum I'm sure you won't mind throwing in the saucer," said Roberto. "The kitten seems so happy drinking from it."
"Nothing doing," said Moishe firmly. "That's my lucky saucer. From that saucer, so far this week, I've sold 34 cats."
