Five surgeons from big cities are discussing who makes the best patients to operate on.

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

The second, from Brisbane, responds, 'Yeah, but you should try electricians! Everything inside them is color coded.'

The third surgeon, from Perth, says, 'No, I really think librarians are the best, everything inside them is in alphabetical order.'

The fourth surgeon, from Canberra 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 Melbourne 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. Plus, the head and the **** are interchangeable.'
