A mid-level executive was so frustrated at being passed over for promotion year after year, that, in frustration, he went to a brain-transplant center in the hope of raising his I.Q. 20 points. After a battery of physical and psychological tests, the center's director told him that he was an acceptable candidate.
"That's great!" the executive said. "But I understand that this procedure can be really expensive?"
"Yes, sir, it can," the director replied. "An ounce of accountant's brain for example, costs one thousand dollars. An ounce of an economist's brain costs two thousand. An ounce of a corporate president's is forty-five thousand. And an ounce of a politician's brain is seventy-five thousand dollars."
"Seventy-five thousand dollars for an ounce of a politicians brain? Why on earth is that?"
"Do you have any idea," the director asked, "how many politicians it takes to get an ounce of brain?"
