Five  surgeons from big cities are discussing

who makes the best patients to operate on. 

The first surgeon, from New York, says, "I like

to see accountants  on my operating table

because when you open them up, everything
inside is  numbered." 
 
The second, from Chicago, responds, "Yeah,

but you should try  electricians!  Everything

inside them are color coded." 
 
The third surgeon, from Dallas , says, "No,

I really think librarians are the best, everything

inside them are in alphabetical order." 

The  fourth surgeon, from Los  Angeles chimes

in: "You know, I like construction  workers.

Those guys always understand when you

have a few parts left over." 
 
But the fifth surgeon, from Washington  DC,

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."
