The line comes from The Fellowship of the Ring, released in 2001 and directed by Peter Jackson, adapted from J. R. R. Tolkien. In the film Gandalf faces the Balrog so the others can escape Moria, and the moment became one of the trilogy's most quoted scenes. Clips and remixes spread through forums, YouTube edits and meme pages in the following years, often misquoted as fly you fools in place of other readings. Its lasting appeal is the mix of genuine peril and over the top seriousness applied to trivial escapes.
