The Flash is stepping down from the Justice Society, because he got his own comic book (that's how things worked back then!!).
So who wants to replace him?
Ladies and gentlemen, Gardner Fox invented gangster rap several decades early!!
Of course, the JSA soon found out that it wasn't funny, as Johnny's misadventures uncovered many actual criminal enterprises, which required the heroes to get off their butts and actual fight crime.
NOTE: Is there anything more chilling than the Spectre's "Ho-ho-ho" "Ha-ha-ha!"?? I mean, do you really want this guy playing practical jokes...?
