Five surgeons are discussing as to who makes the best patients to operate on.
The first surgeon says, "I like to see accountants on my operating table because when you open them up, everything inside is numbered."
The second says, "Yes, but you should see electricians! Everything inside them is color coded."
The third surgeon says, "Well, I really think librarians are the best; everything inside them is in alphabetical order."
The fourth surgeon jumps in, "You know! I like construction workers. Those guys always understand when you have a few parts left over at the end and they understand when the job takes longer than you said it would."
The fifth surgeon shuts them all up when he proclaims, "You're all wrong. Politicians are, without a doubt, the easiest to operate on. They have no guts, no heart, no balls, no brains, no spine.. and the head and the ass are interchangeable."
