A man walks into an antique store, and starts looking around. All of the sudden he spots a huge brass rat in the corner. He's interested in it, so he brings it to the cashier.
"The rat, eh?" says the old, gray-haired cashier.
"Um, yeah... how much?" replies the customer.
"Well, five bucks for the rat--but 200 dollars for the story, " the cashier replied.
"I'll just take the rat, without the story, " the customer says.
He leaves the store, his precious brass rat tucked under his arm. Soon he begins to notice that a few rats are following him. He walks a few more blocks and the number of rats behind him increased. This continued, until there were virtually millions of rats behind him. Afraid of the rats following him, the man ran to the sea and threw the brass rat in. All of the rats plunged in after it, and met their watery deaths.
The man ran back to the antique store. The old cashier was chuckling to himself. "So now you want the story?"
"Nah, " said the customer, "I was hoping you might have a brass lawyer for sale though?"
