The line comes from The Lord of the Rings: The Two Towers from 2002, where Legolas tells Aragorn the Uruk-hai are taking Merry and Pippin to Isengard. In 2005 the scene was remixed online into a techno loop that repeated the line and turned Isengard into a stuttering hook. Shared on early video sites and forums, the remix became one of the first Lord of the Rings memes and is still quoted whenever a group sets off on an unlikely journey together.
