For instance, have you considered the Intestinal Bungee method?

I invented that technique years ago, but it remains a favourite. Has to be done quickly though so the subject doesn’t die early.
It is the one where you take the target to a high bridge or equivalent elevated construction. You then make an incision in the body cavity, cut the digestive tract at the duodenum, then draw it out through the incision.
You then securely affix the severed digestive tract to the railing… and push the subject over the edge.

If you’re lucky, you get to see their intestines uncoiling out of their body as they plummet downwards… until the only thing left holding them up is the internal connection of their rectum to their anus. If you’re unlucky… it snaps or otherwise rips. Either way though… very cathartic.

Then of course there is the Featherhook Technique… but that one is a bit complicated. I’ll explain it some other time.
