Four surgeons sit around discussing their favorite patients.
The first surgeon says, "I like operating on librarians. When you open them up, everything is in alphabetical order".
The second surgeon says, "I like operating on accountants. When you open them up, everything is in numerical order".
The third surgeon says, "I like operating on electricians. When you open them up, everything is color coded."
The fourth surgeon says, "I like operating on politicians."
The other three surgeons look at each other in disbelief.
The fourth surgeon continues, "Because they're heartless, gutless, spineless, and the ass and head are interchangeable."
