Five surgeons are discussing who the best patients are to operate on.
The first surgeon said, "I like to see accountants on my operating table because when you open them up, everything inside them is numbered."
The second responded, "You should try electricians! Everything inside them is color-coded."
The third surgeon said, "I really think librarians are the best; everything inside them is in alphabetical order."
The fourth surgeon chimed in, "You know, I like construction workers...they always understand when you have a few parts leftover in the end, and when the job takes longer than you said it would."
But the fifth surgeon shut them all up with this observation, "You're all wrong. Politicians are the easiest to operate on. There are no guts, no heart, no spine and the head and butt are interchangeable."
