Five surgeons from big cities are discussing who the best patients to operate on are.
The first surgeon, from New York says, I like to see accountants on my operating table, because when you open then up, everything inside is numbered.
The second, from Chicago , responds, Yeah, but you should try electricians! Everything inside them is color coded.
The third surgeon, from Dallas , says, No I really think librarians are the best, everything inside them is in alphabetical order.
The fourth surgeon, from Los Angeles chimes in: You know I like construction workers, those guys always understand when you have a few parts left over.
But the fifth surgeon, from Washington , DC 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, and the head and the ass are interchangeable
