I don’t think I could find it, but there’s a different, older version of this meme with the same pic. The punchline is indeed the first part of this one, but it was done in a much more subtle way and didn’t ruin the joke by spelling it out with “murder instead of suicide.”
Shame on whoever stole the joke and then not only told it badly, but ended it with necrophilia.
When I read your comment, I internalized “sorted” as “sordid.” I guess either one works!
