Basically, there is an entire subset of the population that adamantly believes The Berenstein Bears (I refuse to believe it's spelled with an "a" dammit!) is spelled incorrectly.Take a cold hard look at the wording above. Does something look wrong to you? Do you remember it being Berenstein with an E, not Berenstain with an A?
If you do, you're not alone. There are many who remember it this way. In fact, there are so many Berenstein believers that people in the know will cite that as proof that this is a glitch in the matrix.
A similar large group of people also believe that the word "dilemma" is spelled "dilemna", myself being one of them too.
One of the arguments for this mass confusion is the alternate universe theory.
