I remember a VERY VERY long time ago seeing Ollie Hopnoodle's Haven of Bliss on the Disney Channel (probably very late 80s) and not realizing the first two viewings that it was a sequel to A Christmas Story. Then years later I saw another sequel called It Runs In The family or Our Summer Story or something like that with Charles Grodin and one of the Culkin kids was Ralphie. I honestly thought It Runs In The Family it was a pretty good movie if you pretended the original didn't exist but that's just my opinion. Ollie Hopnoodle's was interesting for what it was, but I just never associate it with A Christmas Story even though Jerry O'Connoll is Ralphie as a teen.
Interestingly enough today I saw on Facebook a kind of Mandela Effect about the first film. I guess you'd call it that or literally just a few people misheard it. There's a number of people that think that the old man said "Must be French" instead of his line about Fragile being Italian.
