The Steve Englehart/Marshall Rogers run on DETECTIVE COMICS comes to its conclusion with a two-part classic pitting Batman against the Joker. This time, the Clown Prince of Crime has infected the world's fish with a variation on his Joker venom, giving every fish a hideous grin. Joker's plan is to copyright the "laughing fish" and rake in the bucks every time somebody buys one.

It's an utterly nonsensical plan -- something the narration calls out a couple times -- but that's the point. The Joker is, at this point in continuity, one hundred percent insane. I'm not sure when it was decided that the character was clinically insane... I know he wasn't in his earliest appearances, since at one point Bob Kane and Bill Finger sent him to the electric chair (and if a criminal is certified insane, they can't receive the death penalty), but by the seventies, he's absolutely there. It was Denny O'Neil and Neal Adams who had the character escape from an upstate asylum in "The Joke's Five-Way Revenge", but I just don't know if it was ever previously stated that he was crazy.

But in any case, "The Laughing Fish/Sign of the Joker" is absolutely the craziest we've seen him in our jaunt through the seventies -- and while I do like the idea that he would come up with a scheme that makes not an ounce of sense to any normal-thinking human, I can't say that I wholeheartedly approve of Englehart's version of an insane Joker. I'd go so far as to say that, more than "Joker's Five-Way Revenge", this is where the modern-day Joker, a character who makes me extremely uncomfortable, was born. In fact, I can pretty much pinpoint the exact panel when it happens:
