Five surgeons discussed who are the best patients in an operating room. The first surgeon says: "I like to operate accountants, because, when you open them up, everything is ordered by numbers."
The second surgeon answers: "Yes, but the electricians are better, because all the organs are color coded, so there is no way to make mistakes."
The third surgeon adds: "No, the librarians are better: inside them everything is ordered alphabetically."
The fourth says: "I must disagree mechanics are the best, they bring the spare parts that must be replaced."
The fifth, finally, says:
"I am sorry to dissent with everyone, but comrades, politicians are the best patients in the world to operate on. They have no heart, no stomach, no balls, and in addition, the brain and the ass are totally interchangeable.
