The line comes from The Dark Knight, released in 2008 and directed by Christopher Nolan, with Christian Bale playing Batman. During a tense interrogation of mob boss Sal Maroni, Batman presses him about a drug shipment and shouts the question about the other drugs. Clips of the exchange circulated on soundboards and in meme edits, where Bale's intense delivery was separated from the scene. It remains popular because the short question can be reused for any mock interrogation, accusation or search for something missing.
