The line comes from The Many Adventures of Winnie the Pooh, Disney's 1977 compilation of earlier Pooh shorts, where zoo and park style warnings around bears were played for gentle comedy. Clips from the film have circulated for years in nostalgia edits and reaction videos, and this short caution was lifted as a standalone sound for meme use. Its appeal survives because the warning works literally for animals and figuratively for people who should not be encouraged, making it reusable far beyond the original children's story context today.
