For years I was convinced that Curt Hennig’s surname was “Henning”, well into the late ‘90s when I’d “smartened up” in my fandom, so to speak. Likely the first time I’d clocked the correct “Hennig” spelling was when playing WCW/nWo Revenge, and like a tit I assumed the developers had missed an “n” so I edited it to the wrong name, the one I’d been convinced I’d been reading in mags, seeing on TV graphics etc as “Henning”.
You be the judge of whether this is true Mandela effect or just me being an unobservant late-teen.
