Its not a joke. Template

This meme comes from the 2019 movie "Joker". In this scene, Arthur (AKA the joker) is put on a live tv comedy show where he is made fun of by Murray, the host. When Arthur publicly admits he killed 3 men on a subway and tries to defend himself, Murray asks "Whats the punchline?" Where joker responds with "There is no punchline, because its not a joke".
