A man went to a brain store to get a brain to complete a study. He sees a sign indicating the profession of each type of brain. He begins to question the butcher about the cost of these brains.
"How much does it cost for an engineer's brain?"
"Three dollars an ounce."
"How much does it cost for a programmer's brain?"
"Four dollars an ounce."
"How much for a lawyer's brain?"
"$1,000 an ounce."
"Why is a lawyer's brain so much more?"
"Do you know how many lawyers we had to use to get one ounce of brain?"
