The first surgeon, from Manchester , says, "I like to see accountants on my operating table, because when you open them up, everything inside is numbered" The second, from Birmingham , responds, "Yeah, but you should try electricians! Everything inside them is colour coded." The third surgeon, from Edinburgh says, "No, I really think librarians are the best, everything inside them is in alphabetical order." The fourth surgeon, from Belfast , chimes in: "You know, I like construction workers... those guys always understand when you have a few parts leftover." But the fifth surgeon, from London , 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 arse are interchangeable."
