Four surgeons are comparing the type of patients they consider the 
easiest to operate on. The first surgeon says, "I like to operate on 
electricians, because when you open them up everything is color coded."
 The second surgeon says, "I prefer to operate on accountants, because 
when you open them up everything is numbered."
The third surgeon says, 
"I think librarians are the easiest to operate on because everything 
inside them is in alphabetic order."
The fourth surgeon says, "I've got 
you all beat. I like to operate on Republicans best. They are by far the
 easiest because they have no guts, no heart, no spine and their mouths 
and assholes are interchangeable.
