Time Travel.
Of course. Some time traveler from the future went back in time and changed history. Only, some people have a special mind that recalls facts from the alternate timeline. Before you say that’s ridiculous, it’s as plausible as someone in 600 AD saying that there are people “Allergic” to Wi-Fi.

I thought it was Stein…
MY CHILDHOOD IS A LIE?!
/s, IT’S STEIN NOT STAIN NO NO NO

Aw man I was about to post this!

It’s always been Berenstain. People just always thought it was Stein because “Stain” is such an unusual ending to a name. the reason for that is the Author’s last names were Berenstain, and they named the characters after their own family.
Or maybe the boundaries of reality are weakening and our multiverse is folding in on itself causing true chaos to be unleashed apon existence as we know it.
