英语笑话:The Cat and the Saucer

An antiques collector was passing a small shop when he noticed a cat on the sidewalk out front, licking milk from a saucer. The man immediately realized the saucer was very old and valuable. He stepped into the shop with an uninterested look and asked to buy the cat. "I'm sorry, " the shop owner said, "but the cat is not for sale: "　　"Please, " the collector urged, "I need a cat around my house to catch mice. I'll give you 20 dollars. " 　　"The cat is yours," the owner said taking the money. 　　"Listen," the collector added, "I wonder if you could throw in that old saucer as well. The cat seems to like it and I'd hate to have him give it up. " 　　"Sorry," the shop owner answered, "but that saucer brings me luck. Why, just this week I've sold 68 cats!"
