I wonder if anyone has ever studied the scathing eulogy as a genre. Ken Layne's piece on Jesse Helms on AOL's Political Machine is a textbook example, though:
"He was a hero to bigots and the cigarette corporations, a menace to the poor and downtrodden, and a mean little troll whose heart was so wrecked by wickedness that doctors had to patch it up with coronary valves from a pig... He was mean, cheap, petty and unloved. He was the ugliest kind of bigot and a stain on America. Anybody who says different is a liar."
Barring any other notable events, the 4th of July will forever be remembered as the birth of experimental obituary.
