Five surgeons are discussing who makes the best patients on the operating table. 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, especially when you have a few parts left over at the end, and when the job takes longer than you said it would."

But everyone had to agree when the fifth surgeon observed: "You're all wrong. Politicians are the easiest to operate on. There's no guts, no heart, and no spine, and everything else is interchangeable."
