Matt Berry plays Laszlo Cravensworth in What We Do in the Shadows, the television mockumentary following a household of vampires living on Staten Island. Berry's performance mixes old-fashioned grandeur with sudden, modern profanity, which is why short outbursts from the character circulate widely as reaction clips. Fans reuse the doorstep line when a scene needs an instant, comic rejection rather than a polite refusal. Its popularity rests less on one viral moment than on Berry's recognisable voice and the show's cult following, keeping it useful for door, visitor and interruption jokes long after first broadcast.
