The sound comes from Disney's 1992 animated film Aladdin, during the musical number Prince Ali performed by Robin Williams as the Genie. In the scene Aladdin arrives in Agrabah under his invented royal identity, Prince Ali Ababwa, with a huge parade meant to impress Princess Jasmine. The stretched announcement became a reusable meme clip online because the overblown fanfare contrasts so well with modest entrances. Editors still lift this moment for reveals, transformations, and introductions where the joke depends on treating someone like visiting royalty.
