He became a stand-up comedian to support his pregnant wife, but failed. He then joined a group of criminals robbing ACE Chemicals, only to find out his wife died. He then encountered Batman and jumped into a vat of chemicals to escape, but the chemicals gave him the appearnece of a clown. This, combined with his wife's death, drove him insane. That's why he's a tragic villain.
