Last laugh

Have you ever looked at your screen and just wondered why?

What does the joker find so funny?

There is,that obvious answer you could give your self ,you could simply Decide 'his crazy.' and call it a day but no that's just too dull and the Joker has always been....quite colorful.

If your here that means you have enough doubt or the interest to ask if your just not in on the joke....

This story of the Joker was
inspired by a fan theory,that does not belong to me.

and it will never let you look at him the same again....
