Five surgeons were taking a coffee break and were discussing
 their work. The first said, "I think accountants are the easiest to
 operate on. You open them up and everything inside is
 numbered."

 The second said, "I think librarians are the easiest to operate on.
 You open them up and everything inside is in alphabetical
 order."

 The Third said, "I like to operate on electricians. You open
 them up and everything inside is color-coded."

 The fourth one said, "I like to operate on lawyers. They're
 heartless, spineless, gutless, and their heads and their butts are
 interchangeable."

 Fifth surgeon said, "I like Engineers...they always understand
 when you have a few parts left over at the end..."
