Ah, the 60's. A time of peace, love and superheroes undergoing random transformations every other week. Whether it's Wonder Woman being turned into a gorilla by alien gorillas (and not by Gorilla Grodd because that actually would have made sense in a "that makes no sense anyway" kind of way), Lois Lane using a machine to make her a black woman (yes, that happened) or everything that happened to Jimmy Olsen for a straight decade, DC comics were obssessed with turning their characters into something that wasn't a superhero. However, today on What Were They Thinking (the place where we look at all of the stupidest, most ill-advised things in comic book history), we're taking a look at Batman. Or rather, as the cover to Batman issue 147 says quite clearly; Bat-Baby.
