Surgeons

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. Plus, the head and the ass are interchangeable."
