"Cat For Sale" joke

In front of a delicatessen, an art connoisseur noticed a mangy little kitten lapping up milk from a saucer. The saucer, he realized with a start, was a rare and precious piece of Ming Dynasty china.

He strolled into the store and offered five dollars for the cat. "It's not for sale," said Morris the proprietor.

"Look," said the collector, "that cat is dirty and undesirable, but I'm eccentric. I like cats that way. I'll raise my offer to ten dollars."

"Make it twenty and it's a deal," said Morris, and pocketed the $20 on the spot.

"For that sum I'm sure you won't mind throwing in the saucer," said the antique connoisseur. "The kitten seems so happy drinking from it."

"Nothing doing," said Morris, the deli owner, firmly. "That's my lucky saucer. From that saucer, so far this week I've sold 32 stray cats."
