That's a good find. Yeah, it's got to be satire. Check out some of the 'testimonials':
From Roy: "I got me some blood put in after I cut three fingers off with a putty knife.Ê The nurses tell me that the blood didn't have no AIDS, but they didn't tell me it come from some unbeliever. Man sure must've been a sinner, because as soon as they got me out of the hospital I was cussing. Drinking. Fighting. Prowling around like an itchy cat."
