Matt Berry plays Laszlo Cravensworth, one of the vampire housemates in the mockumentary series What We Do in the Shadows, which expanded the world of the 2014 film of the same name. Berry became one of the show's most quoted performers thanks to his exaggerated delivery and deadpan confidence. Short lines like this one spread widely as reaction clips and soundboard favourites among fans, shared in edits long after broadcast. The combination of a familiar character and a simple, accusatory question keeps it useful for jokes about secrets and suspicious behaviour.
