to make it more complicated, i f you wanna go with the altered timelines theory, i suggest that there is/are more than 1 or 2 timelines. the only reason i say this is because of the bernstein/berenstein/berenstain bears. of the people who remember something other than the "berenstain bears", a few remember "bernstein" before the change to "berenstein", and THEN to "berenstain". o_O
