The line comes from The Shawshank Redemption, the 1994 prison drama directed by Frank Darabont and adapted from a Stephen King novella. Morgan Freeman plays Red, a long term inmate at Shawshank State Penitentiary who explains that every prisoner claims innocence, leaving him as the supposed exception. The film became a lasting favourite through home video and television repeats, and its dialogue entered meme culture years later. Short clips of Red's admission now circulate on soundboards and social video as a ready made confession joke.
