A man walked into a curio store and was shopping around.
After a while, he chose a brass rat and brought it up to the
counter. The proprietor said, that
will be $10 for the brass rat
and $1,000 for the story behind it. The man said, "Thanks, but
I'll just pay the $10 and pass on the story." He purchased the
brass rat and left the store.
As he was walking down the street, he started noticing all
sorts of rats following him. The further he walked — the
more rats followed. He walked down to the wharf and still more
rats came out and followed him. So, he decided to walk out into
the water, which he did — and all the rats
drowned.
He returned to the store shortly and when he walked in, the
proprietor said, "Ah ha! You came back to pay the $1,000 for the
story, right?" "No," replied the man, "I came back to see if you
have any brass lawyers!"
