Oversmart

A famous art collector is walking through Greenwich Village when he notices a mangy old cat lapping milk from a saucer in front of a store. And the collector does a double take when he sees the saucer. He knows it's very old and very valuable.

So he saunters casually into the store and offers to buy the cat for two dollars.

But the store owner says to him, 'I'm sorry, but the cat isn't for sale.'

And the collector says, 'Please. I need a hungry old tomcat around the house to catch mice. I'll give you ten dollars for him.'

And the owner says, 'Sold,' and takes the ten dollars.

Then the collector says, 'Listen, I was wondering if, for the ten dollars, you might include that old saucer. The cat seems to be used to it. It'll save me a dish.'
And the owner says, 'Sorry, buddy. That's my lucky saucer. So far this week, I've sold sixty-eight cats!'
