Squidward’s Suicide
Story time: there’s a Creepypasta meme telling the story of Squidward attempting suicide, which is meant to be spooky, and which certain sections of the internet love. In one episode of the show, this meme is deliberately referenced, as an image of Squidward’s eyes, large and dripping with something black, appear on a screen of static. Kids might be a bit freaked out, but adults get that this joke is just for them.
