"War Pigs." The Prince of Fucking Darkness weighs in on Bush:

MANSFIELD -- Ozzy Osbourne's traveling metal circus -- better known as Ozzfest -- came ringing into town yesterday with 20 bands, 20 trucks, 40 buses, 525 crew members, and nearly 14 hours of music. It started early, ended late, and touched every style of metal from old-school Black Sabbath and Judas Priest to the speed-core, noise-core, and whatever-core played by young bucks looking to make a name for themselves on a second stage where decibels and testosterone were pushed to the max.
....
And Osbourne, who looked much better than he did last time, startled some fans with video to his opener, "War Pigs," which juxtaposed photos of George Bush and Adolph Hitler, with an unprintable caption about how they resemble each other.

Here's the first verse to "War Pigs":

Generals gathered in their masses
just like witches at black masses
evil minds that plot destruction
sorcerers of death's construction
in the fields the bodies burning
as the war machine keeps turning
death and hatred to mankind
poisoning their brainwashed minds
Oh lord yeah!

This, of course, has the freepers all throwing a fit. And just for kicks, here are the "Top 12 telling parallels between Ozzy Osbourne and George W. Bush."
