Five surgeons are discussing the types of people they like to operate on.

The first surgeon says: "I like to see accountants on my operating table because when open them up, everything inside is numbered."

The second surgeon responds: "Yeah, but you should try electricians! Everything inside them is colour-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 engineers; Those guys always understand if 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 brains and no spine. Additionally, the head and the ass are interchangeable."
