7. The Sound Of One Hand Clapping (Adventures Of Superman 14)
Another story set in the early days, this comic finds the Joker threatening to blow up the Daily Planet just so he can meet Superman. This is truly a Joker story unlike any other, because Superman is such a different audience for Jokers ravings. Unlike Batman, Superman actually takes time to listen and engage with what the villain says, pointing out faults of logic and laughing at jokes in equal measure. And Joker actually squirms under the even-handed scrutiny. Its weird coming away from a Superman comic feeling like Joker is the more boring character of the two, but this well-written story might convince you.
