...Now let's, get this shit clear once and for all
Ain't no terrorist that's bigger than America's balls
Ain't no terror more terrible than terror we brought
And ain't it terrible the terror's all America's fault
I'm askin', what would you do if you knew of it all?
If you knew all our enemies were made for the part?
If you knew that everything they do is part of a plot
That's pre-agreed upon with us, so you always support?...
