Batman # 25 (1944)

It's a good old fashioned villain team up, folks!

And also the first appearances in this collection of two classic Batman Villains. Those being The Joker and The Penguin. After having his robbery foiled by Batman and Robin (hey, Robin's here!) The Penguin gets thrown in jail, winding up in the same cell as The Joker. The two argue over who's the best villain and decide to break out of jail and have a little contest: whoever can steal the prized emerald first wins.

They break out and both try for the emerald, but in attempting to sabotage each other, they draw Batman and Robin to the scene. They escape and agree to work together to kill Batman and Robin, but can't decide on how, getting into an argument and allowing the dynamic dup to break free and beat them up. Worth noting, Penguin wants to water-torture Batman and Robin which is surprisingly hardcore.

One of the Greatest Batman Stories of All Time?: Eh, it's okay.
