1) removal of the frontal lobe of the brain, causing the "patient" to lose all capacity for higher thought, reason, etc. while still technically not considered a "vegetable".
2) a process that had been deemed unethical and barbaric, but has evidently been stealthily carried out on a truly massive scale, as shown by tell-tale symptoms of lobotomization such as:
"Calvin pissing" stickers, voting Republican, obsessive interest in NASCAR, membership in the NRA (as opposed to responsible hunting, fishing, and conservation groups), calling it "moral values" to tell lies in order to start unnecessary wars that kill or maim tens of thousands of people as well as to lie, cheat, and embezzle in a manner befitting of Enron, Halliburton, Arbusto Energy, or Tyco, to destroy God's Creations with irresponsible & reckless abandon, especially while simultaneously ignoring all principles of science and all available facts in order to promote a theocratic worldview in the guise of "intelligent design" (an indoctrination ironically similar to the Islamic fundamentalist wackos these same so-called Christians purport to be opposed to), promote the hatred of and discrimination against the economically disenfranchised or otherwise most vulnerable members of a society, particularly if it allows titillating discussion of sexual acts these same repressed prudes and closet-cases secretly fetishize under the flimsy pretense of "taking a moral stand".
That Dubya's a walking, talking lobotomy.
