The line comes from What We Do in the Shadows, the FX mockumentary comedy spun off from Taika Waititi and Jemaine Clement's 2014 film, where Matt Berry plays the vain, old-fashioned vampire Laszlo Cravensworth. Berry's theatrical delivery turned Laszlo into a fan favourite, and short quotes from the show circulate widely on soundboards, TikTok and meme edits. This particular claim about goblins fits the show's running joke that ancient vampires treat folklore as settled fact, which is why fans keep reaching for it whenever something feels faintly supernatural.
