Five surgeons are discussing who the best patients are to operate on.
The first surgeon said, "I like to see accountants on my operating table, because when you open them up, everything inside them are numbered."
The second responded, "You should try electricians! Everything inside them are color coded."
The third surgeon said, "I really think librarians are the best; everything inside them are in alphabetical order."
The fourth surgeon chimed in, "You know, I like construction workers...they always understand when you have a few parts left over in the end, and when the job takes longer than you said it would."
