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 I 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 butt are interchangeable.
