I don't believe the USDA-inspected stuff has assholes in it. Faces, probably, but no assholes. When I went through a school for food inspection, they made us try unusual (to most folks here) foods. I got lots of leftover camembert because other people thought it tasted like snot. Having never eaten snot, I loved the cheese. The one thing I wouldn't touch was head cheese. They had a particular brand that had big chunks of parts, sliced. It was more of a cross-section type of thing you'd see in a lab. I didn't like the looks of the round puckered things. They were probably just noses.

As to scrapple, I only had it once. We had an office camping trip, and my boss brough some his brother had sent him. Wonderful stuff, fried in an iron skillet over a campfire!
