The title is a playful twist on a familiar movie whodunit phrase, swapping in Donald Duck for an instantly recognisable cartoon reference that needs no explanation online. Short clips built around a single recognisable name or joke travel well on soundboards and in short-form video, because creators can reuse the same beat for blame, reveals and mock accusations without adding context. That reuse is why this kind of clip keeps appearing in memes and edits, even when viewers do not know a single original source for the audio itself.
