The line comes from Tintin, the Belgian comic series created by Hergé in 1929 and later adapted for television and film. Dupond is one of the identical twin detectives Dupond and Dupont, bowler hatted policemen known for confident statements and constant blunders. In French, je fais feu means I am opening fire, a phrase that sounds especially stiff and official in their voices. The excerpt later circulated online as a standalone French meme clip, shared on soundboards and reused in edits far beyond the original scene, helped by how recognisable the Tintin delivery remains.
