The line comes from Jurassic Park, the 1993 film about a dinosaur theme park, and is spoken as characters watch a herd moving across the landscape. The moment stuck because it pairs a simple observation with a huge, awe-filled reveal, and short audio clips from the film later spread across soundboards, meme pages, and video edits. Creators kept returning to it whenever a real crowd behaved like animals in a herd, from concert audiences to shoppers, friends, and commuters, which is why the brief quote still works decades after the film.
