Four well known surgeons were discussing which type of patient was the best on which to operate.
The first surgeon says, "Oh, by all means, accountants. You open them up and everything is numbered."
The second surgeon says, "Engineers ... You open them up and everything is color coded."
The third surgeon say, "Librarians ... You open them up and everything is in alphabetical order."
Everyone looks at the fourth surgeon because they all know he's the designated surgeon for President Bush. So, the fourth one says, "I can't devulge anything due to doctor-patient confidentiality. But I can say that politicians are by far the best. They have no brain, no heart, and no guts. Plus, their heads and asses heads are completely interchangable."
