Y-9D was government code for "people grindings"

Well sir, ah'm just a simple country meat farmer, but ah'll be hogtied if Y-9D ain't the best chemical additive we ever done shoved intah a dead pig to prevent spoilage. Ah fergits what them fancy city folks call it, but th' country embalmer orders it by the case, an' if it's good enough fer Ol' Stuffy, it's good enough fer me!

It is depressing that the soundtrack is more authentic and listenable than 98% of modern 'country'.
