Four surgeons were taking a coffee break and were discussing their work.

The first one said, 'I think accountants are the easiest to operate on. Everything inside is numbered.'

'I think librarians are the easiest,' said the second surgeon. 'When you open them up all their organs are alphabetically ordered.'

The third surgeon said, 'I prefer to operate on electricians. All their organs are color coded.'

The fourth one said, 'I like to operate on lawyers. They're heartless, spineless, gutless, and their head and ass are interchangeable.'
