A man went to a brain store to get some brain for dinner. He sees a sign remarking on the quality of proffesional brain offerred at this particular brain store. So he asks the butcher:

"How much for the Engineer brain?"
"$5 dollars an ounce."

"How much for the doctor brain?"
"$7 dollars an ounce."

"How much for the lawyer brain?"
"$100 dollars an ounce."

"WOW! why is the lawyer brain so much more?"

"Do you know how many lawyers you need to kill to get one ounce of brain?"
