3. Joker’s Last Laugh
Here’s a good one that’s always forgotten.
In the story, The Joker is an inmate at The Slab. A doctor gives him some news: He’s suffering from an inoperable brain tumor, and he’s going to die. So he decides to go out with one final big boom by infecting the other inmates with his own Joker Venom to Jokerize them. So a bunch of C and D-List villains pop up, looking all Joker-y, and try to kill some superheroes.
He eventually figures out a way to Jokerize people through the rain, which is flipping terrifying, and his rampage intensifies. While investigating, Black Canary finds out that the Joker’s X-rays were doctored (heh) to make it look like he was dying, in hopes that it would give him a new lease on life. Sooooooooo, those doctors are fired, right? Like, sooooooooo fired.
Lasting Impact: Not a ton. Some villains die, but for the most part nothing’s changed. But, hey, who says anything has to?
