But the biggest Joker story I remember was in a tabloid sized coloring book that I had.
The Joker had decided that he was going to commit crimes that were related to sadness instead of laughter. I vaguely remember that he even had a Joker-mobile.
The attraction of the book was supposed to be the back cover which was a Batman action shot.
Al I know is that I cut it off, and then carried the comic around without a back cover.
