The Mandela effect is fake.

I can explain every one of these claims, quite accurately, as a matter of fact. In all cases, they are brought about by the inept memory of a clod. 1. The "Berenstain Bears" thing is one of the stupidest and popular arguments for the Mandela effect. As with most cases, it deals with a subtle misspelling that, when brought up, confuses the mind and implants a false memory. This is not brought about by the crossing from one dimension to another, it is a tiny, almost imperceptible quirk. Imbeciles think that the name of these bears is "BerenSTEIN" with an E only because of the popularity of FRANKENSTEIN, who has been heavily popularized in modern media. Because of this, any small deviation from the normal spelling leaves people feeling berserk. The books are named after Stan and Jan BERENSTAIN, with an A, and their names can be spelled however the hell they want them to be spelled. Assuming that their names are spelled incorrectly is doing them a great injustice. The books have always been spelled BERENSTAIN, not BERENSTEIN, and we must accept that we simply never noticed it, and that it does not impact the quality of the books in any way. 2. Darth Vader's quote to Luke Skywalker in episode 5 of Star wars is exactly what you said it was. The quote is, in fact, "No, I am your father." But this is not due to the altering of reality. People remember this quote incorrectly because, shortly after the film came out, Star Wars fans spread the line like a virus until it became the most well remembered thing about the series, and now, due to our mass stupidity, a sharp call to reality disturbs our brains, so, to comfort ourselves, we say that there is a universe in which that line was the actual line. It never has been, though. People probably only put "Luke, I am your father" as the correct way because it sounds more dramatic, and so we know who Darth Vader is talking to. The line is actually how it is because, right before Darth Vader mutters the iconic line, Luke says something like "You killed my father!" So, in this case, it would make less sense for Vader to simply blurt out, "Luke, I am your father." Instead, he responds to Luke's statement, saying that HE is the father instead. Honestly, the difference doesn't matter. It means the same thing either way, and there are many, many parts of Star Wars that people don't remember, simply because of the huge universe that George Lucas created, so you can go on spouting that iconic line if you want to. It's just a small alteration from the script. 3. Everyone grew up watching "Looney Tunes". There has never been a show called "Looney Toons". This error probably dates back some time, because, of course, people are idiots, but this difference cannot be attributed to an alternate reality. The show was called Looney TUNES because, at the time of its creation, Warner Brothers was trying to compete with Disney's animated short series, "Merrie Melodies". Since its creation, the series has relied heavily on music, which can be seen in the episodes "One Froggy Evening" and "What's Opera, Doc?" among others. It functioned as a kind of satire of Hollywood musicals. Bugs bunny was based on Clark Gable. Although its reliance on music has decreased heavily over the years, the name remains the same, because any alteration could upset hundreds of fans. Your pathetic minds only think the title was spelled with two o's because you think of Looney Tunes as nothing more than a cheap cartoon. It's much more than that, it's a comment on American culture, and you're a fiend to blame your ignorance on an inter dimensional barrier. We must keep in mind that stupidity has no valid excuses, and alternate dimensions are the stupidest excuse I've ever heard of. If such an event were to happen, the world would change much more than simply altering the spelling of something. Since there are no "BerenstEin bear" books or "Looney TOONS," There are only two possibilities. Either the entire human race has switched universes, which would probably be somewhat noticeable, or we're a group of stupid, moronic clods who don't know stuff. Seems pretty obvious to me.
