I recently re-watched Beavis and Butt-Head Do America. There’s a part I remember from when I watched it back in the 90s that wasn’t there this time, and I’m wondering if it’s the Mandela effect or if the scene was changed. It’s where Beavis and Butt-Head get on the plane to Las Vegas and meet the Old Lady. I remember her telling them “Las Vegas has more slots (she pronounced it like sluts) than you can shake a stick at.” The line isn’t there on the version available for streaming on Paramount Plus. Was the line ever in the movie or a trailer, or is this the Mandela effect?
The scene was in there.
In that link she says “there’s so many slots you won’t know where to begin.” I have a memory of her saying the line like I quoted above, about there being more than you can shake a stick at. Of course I also remember watching it recently on Paramount Plus, and checking just now I notice it’s not available on Paramount Plus. It is available on Hulu’s premium service, but I don’t subscribe to that so I know I didn’t watch it on their service.
I think they edit scenes in the movie for different audiences or mediums for maximum effect/or mitigating the risk of a controversy/liability.
Also I think the Mandela affect is us noticing the interconnectedness we all share. There are patterns and trends in phenomena and our thought processes that are unique to the human experience. There are similarities in all of us in how we associate things and go through mental processes. Its just a matter of time before those worlds collide. Because we tend to take our perception as the ultimate reality, we attribute something mystique to it (oh shit, someone just cast a spell on us 
). But really its just our shared reality, how we collectively experience it. There are a lot of similarities with actual reality but everything we experience is limited by the boundaries of our perception.
