A cannibal entered the meat market to buy something nice for dinner. The owner greeted him and told him to look around. The cannibal began to inspect the meat case and noticed the market specialized in brain. Upon further inspection he noticed a marked disparity between the costs of brain meats.
A carpenter's brain sells for $1.50 per pound. A plumber's brain sells for $2.25 per pound. He noticed with alarm that a politician's brain sells for $375.00 a pound. With not a little curiosity he asked the owner why the huge difference in price between the similar meats.
The owner responded with a deadpan look on his face, "Do you realize how many politicians it takes to get a pound of brains?"
