Shown up above is the cover to a now ultra-classic comic book, BATMAN #73. This was the issue that introduced "Jokers Utility Belt". This story inspired a "Joker episode" for a 1966 BATMAN TV Show Script, has been reprinted numerous times, and even made an appearance on the recent BATMAN: THE BRAVE AND THE BOLD animated TV cartoon in an episode titled "Emperor Joker".
Well, someone made a set of videos that tell the story. I don't know what the source of the audio is but it seems like some "Story Record" you might have heard as a little kid. If anyone knows, please let us know. But hey, watch the 3 videos, they're fun!
