A man goes into a pet shop to buy a parrot. The shop owner points to
three identical looking parrots on a perch and says: "The parrot on the
left costs 500 dollars".
"Why, does the parrot cost so much" asks the first man. The owner says
"Well the parrot knows how to do legal research."
The man then asks about the next parrot to be told that this one costs
1,000 dollars because it can do everything the other parrot can do plus it
knows how to write a brief that will win in any court on any case.
Naturally, the increasingly startled man asks about the third parrot only
to be told that it costs 2,000 dollars. Needless to say this begs the
question "What can it do?" To which the owner replies "To be honest I have
never seen it do a thing but the other two call him Senior Partner."
