Four surgeons were on a coffee break. The first said: "I like operating on librarians best because when you open them up everything is in alphabetical order."
The second said: "I think accountants are the easiest because everything inside them is numbered."
The third said: "I prefer electricians because everything is colour-coded."
And the fourth said: "I reckon lawyers are the easiest to operate on because they're heartless, spineless, gutless and their head and their @$$ are interchangeable."
