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.
Someone linked his Wikipedia page elsewhere on this thread. Ofcourse the last part is made up, that's the joke, but the first part is the feel-good meme that made its rounds several years ago.
Fortunately, there's plenty of meme communities here. Just type "meme" into search and start hitting that +. I'd also recommend blocking shitpost communities if you don't like them, especially as it seems you're viewing an uncurated "All". Hope that helps :)
Someone will be asking in a moment to tell us that this is shitpost community, some people are too uptight, that its dark humour, and that we should just block the community if we don't like it.
Only a child can find things like rape and suicide funny, because they lack the emotional depth to understand the ramifications of these concepts.
Well the suicide/murder part was funny.....the raping a dead corpse part was unneeded. I'm not offended or disgusted at all! I just think the last part made the meme worse.
