The Joker

"Ever danced with the devil by the pale moonlight?"
He asks the young boy at his sight

Some people say that to make someone insane
One bad day is enough
The poor clown has never been the same
Since he fell inside that chemical tank

Every story needs a villain
And every hero, an antagonist
Superman's nemesis is Lex Luthor
And Gotham's greatest psycho, a humorist

Doing crimes in a killing spree
Or locked up inside Arkham
The Joker, in prison or free
Is the archenemy of Batman
