The line comes from Jurassic Park (1993), spoken by Samuel L. Jackson as park engineer Ray Arnold. It became one of the film's most quoted warnings, later circulating as a standalone meme clip on soundboards and in short videos, where creators reuse it as a signal that chaos is about to start. Its staying power comes from the combination of a beloved blockbuster, Jackson's deadpan delivery, and a warning that fits almost any over-the-top reveal.
