Newspaper joke

Four surgeons are discussing who makes the best kind of patient to operate on. The first says, "I like to see accountant on my operating table because when you open them up, everything inside them is numbered." The second surgeon responds, "Yeah, but you should try electricians! Everything inside them is color coded." The third surgeons says, "No, I really think librarians are the best. Everything inside them is in alphabetical order." But the fourth surgeon shut them all up by saying "You're all wrong. Politicians are the easiest to operate on. There are no guts, no heart, no balls, no brains and no spine; and the head and ass are interchangeable."
