The first surgeon says: "I like to see accountants on my operating table, because when you open them up, everything is numbered."
The second responds: " yeah, but you should try electricians. Everything inside them is color coded."
The third surgeon says: " No, I really think librarians are the best; everything inside them is in alphabetical order."
The fourth surgeon chimes in; " You know, I like construction workers. These guys always understand when you have a few parts left over."
But the fifth surgeon shut them all up when he observed; " You're all wrong. Politicians are the easiest to operate on. There's no guts, no heart, no balls, no brain and no spine, and the head and the ass are interchangeable."
