One of my jobs growing up, after killing a pig, was to clean out the intestines. I used the “there gotta be more toothpaste in here” method to get all the shit out. Then stuck a hose in there and rinsed it out.
Then I graduated to collecting the blood and having to continously stir it so it wouldn’t coagulate. Fun times. All for something called morcilla…mmmm mmmmm good
