Mrs Doubtfire is the 1993 comedy film starring Robin Williams as Daniel Hillard, a divorced father who disguises himself as a Scottish nanny to spend more time with his children. The character's warm, theatrical voice and larger-than-life greetings became one of the film's most quoted traits, and clips of her entrances have circulated for years on video platforms and soundboards. Creators still reuse the loud hello because it instantly signals a funny disguise, a surprise arrival, or a playful impersonation without needing any setup.
