It’s the height of the Batman tv craze, and that spills over into Action 344 (Dec. 66).
Binder and Boring probably regret having their names associated with this tale. It begins as Superman and Batman hang out and switch brains. It’ll be fun! Oops, look what a klutz Batman is in Superman’s body. Ha ha. Groan.
Then Superman starts having dreams, which are really easy to “decode” as referring to Batman’s enemies. The Joker is the first, with squirting flowers, white faces, and laughing mania. The Riddler dream sees a sphinx.
The last dream flirts with the idea of the Penguin. Superman has no idea what is going on, and starts freaking out.
Batman explains it all. When in Superman’s body, he spilled red kryptonite, which induced dreams based on the flash cards of Batman villains he had been showing Superman.
Yeah, ok. I guess it could have been worse.
