Here's one which may be Mandela Effect, but certainly exists in my head - if it was real I'd love to see it again, and also find out how it was achieved.
I'm pretty sure it was an episode of Tomorrow's World in the mid 90s - possibly one of the Megalabs. They played a VT, and then invited people to phone in to a televote number to give their opinion on something in it. But at the end, they revealed that they'd played a different version of the VT in different parts of the country, which is why they had different results in each region.
The bit I remember for sure is seeing a bit of a glitch in the picture before the VT started (and another after it), which gave me both a 'I wonder what that was?' followed by an 'aah, that's what that was!' when they did the reveal.
