(NSFW) Hypothetically, what would be the best way to dispose of a body on the sly (would be useful for a story)

I’m always looking for creative ways to remove characters from my stories, so any input would be appreciated.

There are so many methods:

Feeding it to pigs
Incinerating it
Burying it
Dumping weighted into a body of water
Sealing it in concrete
Etc.

What are the pros and cons? Which method would you choose for your story and why?
