There are many possible origins for the Batman villain The Joker--the most known one is that The Joker was originally a failed comedian who took to a life of crime as The Red Hood. While being persued by Batman, the Hood falls into a vat of acid which disfigures him. There are holes in Joker's origin so future writers can add their own spin to the origin but I'm sure no writer would've come up with The Joker just putting on whatever lipstick Hattie is wearing here and then robbing a bank after murdering his next door neighbor.
