No single film or show is credited for this recording, and it circulates online simply as a generic old man mumbling effect. Short, loop-friendly mutters like this became common on soundboards and in meme edits because they need no context to land: the tone alone signals confusion, forgetfulness or low-level grumbling. Creators drop it over game characters, pets, teachers and grandparents alike, often sped up or slowed down slightly. Its popularity comes from that flexibility, letting one indistinct ramble stand in for any moment where someone clearly has thoughts but cannot quite form them.
