One blogger has put the Dean scream to music (turning Vermont's fiery former governor into a kind of late 80s party dude) and, by all accounts, it now exists as a car alarm. There is an alternative 'house' version, though it has the musical qualities of the preset rhythms on a Casio keyboard.
Live by the internet, die by the internet. Years from now, if and when his name comes up, people will say, "hey, wasn't he the one with the Scream?"
UPDATE: This is not going away.
UPDATE: And. And. (Of course, James Taranto made a fool of himself with his al Qaeda cheering section, so he's not entitled to ridicule anyone for awhile now.)
UPDATE: Hey, that MSNBC article also uses "Live by the internet, die by the internet."
