Matt Berry plays Laszlo Cravensworth, the flamboyant English vampire, in the FX mockumentary series What We Do in the Shadows, which began in 2019. The phrase don't mind if I do is a long-standing polite English expression, but Berry's theatrical, old-world delivery gave it a new life as a reaction sound. Clips of his voice have circulated widely on soundboards and in short-form video edits, where creators use it to mark a moment of shameless opportunism. Its appeal lies in the contrast between perfect manners and obvious self-interest.
