Five surgeons are discussing the types of people they like to operate
on. The first surgeon says: "I like to see accountants on my operating
table, because when you open them up, everything inside is numbered."

The second responds: "Yeah, but you should try electricians! Everything
inside them is color coded."

The third surgeon says: "No, I really think librarians are the best;
everything inside them is in alphabetical order."

The fourth surgeon chimes in: "You know, I like construction
workers...those guys always understand when you have a few parts left over."

But the fifth surgeon 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 ass are
interchangeable."
