I was watching the Salt Bae skit with my teen daughter, and she said, "Oh, that's based on a meme." I went and looked up Salt Bae, and, turns out that the skit wasn't that far off from reality, and that made it all the funnier. I'm always kinda tickled when I think SNL is spoofing a thing, and, turns out, nope, that they are not even exaggerating that much.
Same with the Prank Posse skit. My daughter, who says she lives on the internet, recognized that genre of YouTube channel, right away, and the type of folk they were spoofing.
