Four surgeons are taking a coffee break.
The first one says, "Accountants are the best to operate on because when
you open them up everything inside them is numbered."
The second surgeon says, "Nah, librarians are the best; everything
inside them is in alphabetical order."
Third surgeon says, "Try electricians. Everything inside them is
colour-coded."
The fourth one says, "I prefer NSW fans. They're heartless, spineless,
gutless and their heads and arses are interchangeable."
